Inkscape crahes when textext (LateX extension) element is added

[Lothar Birk]

Hi,

I have a small inkscape sketch (attched) which crashes when I add a
TeX Extenstion (textext.py version 0.44) element.

I run a Linux Mint 13 (64bit) system with inkscape 0.48.3.1 r9886 (Jan 29 2013).

The backtrace for the crash is:
This GDB was configured as "x86_64-linux-gnu".
For bug reporting instructions, please see:

Thanks for looking into this.

Based on the Inkscape version
> inkscape 0.48.3.1 r9886 (Jan 29 2013)
and the id of <sodipodi:namedview> of the provided sample SVG file:
> id="namedview6173"

this is a duplicate report of a known regression in Inkscape 0.48.3.1 (fixed in 0.48.4):
- Bug #944077 “inkscape crashed with SIGSEGV in Inkscape::Extension::Implementation::Script::effect()”
  <https://bugs.launchpad.net/inkscape/+bug/944077>

Workaround for affected files:

Note that the same trigger (id string for <namedview> element) is e.g. present when opening PDF/PS/EPS files in Inkscape for editing, as described in
<https://bugs.launchpad.net/ubuntu/+source/inkscape/+bug/944077/comments/10>

Please add a comment here and revert the duplicate status if you don't agree and think these are different issues.
