Summary: opendir doesn't work?

Initial Comment:
I have downloaded & installed the latest lxr version.

I have 
always preferred python, php or csh-gawk-grep-sed to do scripting 
stuff
over perl, so i will need your help here :)

My problem is 
that when i point my browser to http://localhost/lxr/source
i 
get a message that my src directory can't be read (although it is 
guo+xrw) 
So even though i get the header stuff of the page, etc i 
don't get the contents
of the src dir in the browser.

Error is 
in : lib/LXR/File/Plain.pm line 104

So what can the problem be? 
I know that somehow apache must have access to that 
directory. I 
put a link from /usr/local/lxr to my source dir, so that permissions 
in
.htacess apply to src dir too, but i still can't have access to 
the src dir !!!
How can i solve this ??

Now, i tried to debug 
Plain.pm, by printing some stuff, but the fact is i keep
getting 
the error for line 104 again, although it is now 107! I have diabled 

caching in the browser, so i guess it is apache who has cached the 
Plain.pm 
How can i solve this too??

Many thanks !

Hi,

I have an error reported at the same file, same line number,
i.e. Plain.pm line 104. The complete error message is like this:

** Fatal: Can't open
/home/robbieye/indexed-src/GEANT4/4.0/source/digits hits/ at
/home/robbieye/lxr-0.9.1//lib/LXR/Files/Plain.pm line 104.

I am using LXR 0.9.1 to cross reference Geant4 4.0 package.
Every directory in the source tree is cross referenced and
browsable except for this particular one with a '+' in the
directory name: "digits+hits". So apparently the perl
scripts changed the '+' to ' ' and so the opendir() fails

Now let me explain my story more precisely. So, most of the
things work fine, except for the following case.

When I browse the parent directory of "digits+hits", which is:
http://localhost.localdomain:8080/lxr/GEANT4/source/source/
On the shown page, there is a link to the sub directory
"digits+hits", the link is shown correctly
as:http://localhost.localdomain:8080/lxr/GEANT4/source/source/digits%2Bhits/

Then when I clicked on this link, the returned URL in the
browser's (i'm using Opera) address bar is:
http://localhost.localdomain:8080/lxr/GEANT4/source/source/digits%2Bhits/
So this is still correct. But the return page itself
contains the error message:
** Fatal: Can't open
/home/robbieye/indexed-src/GEANT4/4.0/source/digits hits/ at
/home/robbieye/lxr-0.9.1//lib/LXR/Files/Plain.pm line 104.

Also, the directory title in the page is showed as "GEANT4/
source/ digits hits/", so the '+' is substituted by a blank
space somehow. And when I move my browser to the "digits
hits" portion of this erroroneous link, it reads:
http://localhost.localdomain:8080/lxr/GEANT4/source/source/digits%20hits/,
so the "%2B" is changed to "%20" in the address.

I knew little about Perl to fix the problem myself, can
someone out there help me with this? Thank you very much,
I'd be more than happy to verify your solutions! Actually i
tried to look into the Perl scripts, and I stop at the
function http_wash in file /lib/LXR/Common.pm and comment
out the line: "$t =~ s/\+/ /g;", but the error is still
there(i didn't restart my browser though).
