crash if sans-serif font is a bitmap font

[Bug Importer]

Crash when opening some svg files like add_user.svg from Oxygen project

Segmentation fault. Can`t debug using gdb, maybe because of HyperThreading.
Affects at least 0.45 and up to current svn. Linux-2.6.22.

Works for me.

I have checked again and found that the problem is weakly connected with
file add_user.svg.
In fact it is a very old bug, I sent a message to inkscape-devel mailing
list
(http://sourceforge.net/mailarchive/forum.php?thread_name=200701271320.27119.smpuj%40bk.ru&forum_name=inkscape-devel)
in the end of January describing the problem, but Bryce Harrington couldn`t
reproduce this, I hadn`t enough time to debug and to talk with developers
and simply wrote a script to overcome the problem: it changes the default
on my system bitmap font with ttf font and inkscape don`t crash.
The problem appeared again then I started using oxygen icons. At one step
installer runs this 'inkscape --without-gui --export-background-opacity=0
--export-width=128 --export-height=128 --file=${svg} --export-png=${png}'
and with some of icons it fails with SIGSEGV. Today I replaced in this
command inkscape with inkscape.sh (this is the name of my script, currently
I know it is simpler to use FONTCONFIG_FILE environment variable when to
substitute ~/.fonts.conf file) and the problem disappeared. It is strange
for my why 'inkscape --without-gui' wants to know my 'sans' font but I will
debug it. So I will debug inkscape myself and will send a good bug report
to this tracker soon, so you can close this bug.

PS. About hyperthreading: it is a problem not of inkscape but of gdb:

It is slightly strange for me that you have replaced the topic and closed
the bug at the same time. So I think it is not closed.

These are steps how to reproduce a bug.
Don`t know how to submit a file here so it is there:
http://files-upload.com/files/489380/inkscape.tar.gz
1. Extract inkscape.tar.gz in /tmp folder (this is important because path
is hardcoded in config)
2. cd /tmp/inkscape
3. Run "FONTCONFIG_FILE=/tmp/inkscape/fonts.conf inkscape add_user.svg" in
console. The program should fail.
4. In /tmp/inkscape/conf.d/50-fonts.conf replace "Helvetica" with
"Bitstream Vera Sans". The program should work ok.

I cannot reproduce from your description. Inkscape starts up OK though all
fonts in the interface are different. It als says in the console:

Fontconfig error: Cannot load default config file

I also attached your archive to this bug.
File Added: inkscape.tar.gz

Thank you.
"Fontconfig error: Cannot load default config file" without any other
fontconfig error messages means that $FONTCONFIG_FILE don`t exist.
