Extensions crash

[John Franklin]

Inkscape crashes whenever I run any extensions ( I have not tried every single one, but a few different ones ). Here is the gdb output.

Please provide information about your version of Inkscape, and whether the same crash also happens in a new document just created in Inkscape based on the default template.

Background: Inkscape 0.48.3.1 has a known regression (fixed in 0.48.4) when running any extension in a file which is not based on a default template from Inskcape, tracked in
- Bug #944077 “inkscape crashed with SIGSEGV in Inkscape::Extension::Implementation::Script::effect()”
  <https://bugs.launchpad.net/inkscape/+bug/944077>

For Inkscape 0.48.3.1, a workaround for affected files is described here:
<https://bugs.launchpad.net/ubuntu/+source/inkscape/+bug/944077/comments/11>

Inkscape 0.48.3.1 r9886 (Mar 29 2012)
I believe it is the same as the other Bug #944077 you mentioned. The workaround worked... unfortunately, I have several files which have been saved as svgz which need to be opened and fixed. Thanks!

Thanks for reporting back (much appreciated!).
