inkscape segfaults when saving particular SVGs as PDFs.

[b]

Binary package hint: inkscape

With version 0.47 r22583, built Apr 4 2010 I get the following:

$ inkscape -f DM2-SP.svg -A /tmp/test

Emergency save activated!
Emergency save completed. Inkscape will close now.
If you can reproduce this crash, please file a bug at www.inkscape.org
with a detailed description of the steps leading to the crash, so we can fix it.
** Message: Error: Inkscape encountered an internal error and will close now.

Segmentation fault

Same thing happens when saving PDF from GUI.

Version 0.48.1 r9760 (compiled on this machine from source) Does not segfault on the same file: (but gives hints to the problem):

$ ~/src/inkscape-0.48.1/src/inkscape -f DM2-SP.svg -A /tmp/test
** Message: Invalid glyph found, continuing...

The PDF does get generated and looks fine.

I'll attach the offending SVG file (generated by inkscape, likely a version from a few years ago)

Hi b,

I can't reproduce this in Ubuntu Natty with inkscape_0.48.1-2ubuntu2, so I guess it has been fixed upstream. Please could you try to obtain a backtrace of the crash as described at https://wiki.ubuntu.com/Backtrace ?

Possible duplicate of bug# 564442 <PDF export: crash in 'CairoRenderContext::_showGlyphs'> ?

Yup, looks like a duplicate, I've marked is as so. Here is the BT:
