-- Information about the crash:
I had just updated to Kubuntu 10.04 and was trying to apply two bug fixes. SAX-based renderer library for SVG files (extra runtime) and SAX-based renderer library for SVG files (runtime) for the libsvg2-common and libsvg2-2 respectively.

The crash can be reproduced some of the time.
