The crash happens only when compiled by GCC 4.3, but I can not tell whether it's compiler's fault, or Inkscape's;
It is easily reproducible, just add text object, type some text and press Enter.
Program received signal SIGSEGV, Segmentation fault.

Full backtrace is attached to the Fedora bug referenced above.
Should any more information such as values of variables or core dump and debugging symbols be needed (in case you don't have gcc-4.3 handy, etc.), please let me know.
Description of problem:
I'm seeing inkscape sigsegv after adding a small word with the new text tool and
pressing enter. The backtrace with debuginfo is attached.
Program received signal SIGSEGV, Segmentation fault.

Version-Release number of selected component (if applicable):
inkscape-
How reproducible:
Very consistent, although I do not know if its new with this version (I haven't
been using it).
Steps to Reproduce:
1. add new layer, choose text tool
2. add new text (liberation sans, 16pt), write small word such as 'PCB'
3. press enter, then sigsegv occurs
