Comment 1 Aaron J. Seigo 2011-02-18 17:35:07 UTC

note that you didn't have packages with the full debug symbols installed, and so the backtrace isn't overly helpful. for future reports, it would be good if you could install those packages.

in this case, i actually recognize the crash anyways :) and it's been fixed in later versions.
