Segfault in org.inkscape.color.grayscale extension

[Eric Marsden]

Hello,

Inkscape segfaults when the Extensions / Convert to grayscale action (approximate name; my menus are in French) is selected via the menu, on the attached file. Running under gdb shows

Program received signal SIGSEGV, Segmentation fault.
0x000000000080ad95 in Inkscape::Extension::Implementation::Script::effect(Inkscape::Extension::Effect*, Inkscape::UI::View::View*, Inkscape::Extension::Implementation::ImplementationDocumentCache*) ()

The same operation does not lead to a segfault on simple SVG files.

I am running Inkscape 0.48.3.1 r9886 (packaged by Debian as 0.48.3.1-1.1) on Linux/AMD64.

Based on the version:
> Inkscape 0.48.3.1 r9886
and the id of <sodipodi:namedview> of the provided sample file:
> id="namedview4"
this is another duplicate of a known regression in Inkscape 0.48.3.1:
