Initial Comment:
I just installed Inkscape 0.42 for the first time on a
Windows ME machine. When I try to run it, the following
error appears:
Pango-ERROR **: file shape.c: line 75 (pango_shape):
assertion failed: (glyphs->num_glyphs > 0) aborting...

When I click OK for this error, I get a Microsoft
Visual C++ Runtime Library dialog with the message:
Runtime Error! Program C:\PROGRAM
FILES\INKSCAPE\INKSCAPE.EXE
abnormal program termination.

Seems like an MSVCRT DLL version mismatch in the
WINDOWS\SYSTEM folder. Shouldn't the correct version be
put in place by the installer? Which version is required?

Hello ! 
I had exactley the same error message. That was my first install 
of Inkscape. The next two installs were ok. Where do you got 
the Install-pakage from? Can you go to the console, into the 
Inkscape folder an type in: 
dir /O *.dll > def.txt 
and  upload it here? 
I have seen that in my broken folder the dlls alone are 42MB big. 
In the folder with the working inkscape it is all together about 
16.4MB big. 

I hope it helps. 

Greetings 
Steffen

OK, I ran from the command line. The output was 
Inkscape 0.42+devel (Sep  9 2005)
I grabbed the latest version to see if the problem had fixed
itself. I also tested with the previous version - 0.42.2
(August 23 2005) was the --version output - and had
identical results.

Inkscape is still crashing on startup with the same messages
as in my 09/01 posting. Crashes on startup in exactly the
same way when run from the command line.

Here is the backtrace:

The version of MSVCRT I'm using would seem to be 6.01.0924.
You can find USUALLY out what version is in use by searching
the WINDOWS\SYSTEM folder (for Win 9X) or WINDOWS\SYSTEM32
folder (for Win 2K/XP) for MSVCRT.DLL then checking the file
properties dialog. (Info is displayed on the Version tab.) 

I say usually, because if there is another version of this
file on the system, perhaps hiding in an application
directory, that version may get loaded first and prevent the
"right one" from loading into memory. (Only one version of a
given Windows DLL may be loaded at a time.) Well-behaved
apps are supposed to check the version of MSVCRT (and other
core DLLs) during install, and place their version in the
SYSTEM folder ONLY if it is later than the one that is
already there. But not all apps behave well, as we know. ;-)

To find out which version is currently loaded into memory,
you need the Process Explorer utility from
 http://www.sysinternals.com. I used this to verify that the version
in my SYSTEM folder is actually the one that is in memory
when the crash occurs.

Anyway, the MSVCRT connection was only a guess on my part -
and a fairly uneducated one at that.

That's nice to know. Now if only I were a C++ developer and
knew how to compile X-platform binaries, I'd be all set. ;-)
Sadly, I'm just a lowly end-user and such things are beyond
my abilities.

Is it possible that something in the latest Windows
INSTALLER package is not doing it's job properly? I noticed
that the file size for .42 is substantially smaller than
that for .41. Has something been left out of the install
package that used to be there?

I'd really like to get this working on my system. I've gone
back to 0.41 which runs fine on this system. But I'm running
into compatibility issues when I try to switch SVG files
between the different versions, so I'd like to bring all my
systems up to 0.42-2 if I can. Also, since I'm using
Inkscape to work on a project right now, I'd like to be able
to report any bugs I find, but I can't do this if I'm not
using the latest version on my primary work platform.

One simple thing to try to start with: humour me and try
running inkscape --version from the command-line to verify
that you really are running 0.42.2.  (I'm told you may need
to do inkscape --version > tmp.txt and then type
tmp.txt.)  Then run inkscape (with no arguments) from the
same command-line and reproduce the bug.  It wouldn't be the
first time that I or anyone else had mistakenly run the
wrong version of something.

If you suspect that an MSVCRT DLL version mismatch might be
to blame, then can you indicate what version you're
currently using, and say how someone else can find out what
version they're using?  (I can't help here, as I'm not a
windows user.)

If the problem is because of a DLL version mismatch, then
compiling for yourself should fix the problem.

In case the bug is in inkscape code rather than a build
problem, I've just now added some assertions to the sole
place in inkscape that directly calls pango_shape.  However,
pango_shape can also be called by functions within pango.  A
backtrace might be helpful to see what bit of inkscape code
is responsible for having pango_shape called.  See
http://inkscape.org/report_bugs.php for how to get a backtrace.

Uninstalled .42.1 and installed .42.2. Stilll gettng the
first error:

Pango-ERROR **: file shape.c: line 75 (pango_shape):
assertion failed: (glyphs->num_glyphs > 0) aborting...

When I click OK for this message a second message is displayed:

Pango-ERROR **: file shape.c: line 75 (pango_shape):
assertion failed: (glyphs->num_glyphs > 0) aborting...

Pango-CRITICAL (recursed) **: _pango_engine_shape_shape:
assertion 'PANGO_IS_FONT (font)' failed aborting...

Then nothing.

This is one of the bugs fixed in 0.42.2. Please upgrade.

ALSO: A second message is displayed following the first:

Pango-ERROR **: file shape.c: line 75 (pango_shape):
assertion failed: (glyphs->num_glyphs > 0) aborting...
GLib-GObject-CRITICAL (recursed) **:g_object_ref:assertion
'G_IS_OBJECT (object)' failed aborting...

Clicking OK again produces the MS VC++ Runtime error dialog.
