Comment 4 for bug 631281

Hey, I had the crash with extension->negate->color. With inkscape 0.48 on linux, it tells me "Inkscape encountered an internal error and will close now.", then, well, closes.

I tried to use a recent git version of inkscape (3-4 days ago or so), and though it still do no work, only the python engine crashes.

It pops up a dialog with the following text :

I know naught of python, but 'http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd' definitely do not exists anymore.
Since the script file seems a little outdated, I tried to fix the shebang to #!/usr/bin/env python2 instead of #!/usr/bin/env python, but it did not worked.
