In preview holder req.height is calculated to be 46, then
req2.height is calculated at 48. int
h2=req.height/req2.height; so h2=0. This leads to the
division by zero. adding a line if (h2==0) {h2=1;} allows
inkscape to run. (though this may hide the real problem
which is req2.height > req.height)

I think that it's a good guess that unicode filenames might
be implicated. But I get the same error when starting from a
"regular" directory. The summary might need to be changed
because starting from a directory with unicode isn't the
problem.

However I have got a nice lot of output from gdb, cut and
pasted below.

This was from a clean build I made myself (svn export ...)
from today.

Just a guess: is this also if you start from a dir having no

Summary: fixed length toolbars prevent working on narrow screens

Initial Comment:
Thanks for this great application.

I have a TabletPC laptop with rotatable display (Lenovo
ThinkPad X41 Tablet). Unfortunately inkscape is not
usable in the rotated resolution (768x1024) because the
toolbar forses the window to be too wide.

Attaching a screenshot.

Jon, here's another one for you to close when you fix our
toolbars :)

Summary: Crash on create/drag object with certain snap settings

Initial Comment:
When I have a document with certain snap settings,
creating or dragging a shape will make Inkscape crash
(Segmentation Fault). These are the steps to reproduce:


a) Create new document (or open existing one)

b) Set snap settings as follows: 

Everything off, except:
  Object snapping:
    Snap nodes to object
    Snap to object paths
  Grid snapping:
    Snap nodes to grid
    Always snap
  Guide snapping:
    Snap points to guides

(Illustrated in this  screenshot:
http://www.aphax.nl/images/inkscape/snapcrash.png)

c) Create new, or drag shape

d) Observe crash (internal error/segmentation fault),
if not, then tick off all snapping settings and go back
to step b) (I had to do this once).

Thanks for the quick fix! I can't get it to crash again
after fiddling with various snap settings for a few minutes
(though I haven't tried every possible combination).

Thanks for the quick fix! I can't get it to crash again
after fiddling with various snap settings for a few minutes
(though I haven't tried every possible combination).

Commited a quick fix to Inkscape::ObjectSnapper::_snapPaths, 
did not test all the options to be sure fix is complete

And a "Grid" is in the Effects menu placed twice too. Once 
in the main menu and the second is under the Render submenu.

I forgot: I've noticed this on Windows in the actual svn 
build and several builds before too.
