Getting the same crash (mostly when scrolling) with a fresh install of Gutsy Tribe 5 Kubuntu. My Gutsy Tribe 5 Ubuntu worked fine, so I think it might be Kubuntu-specific.
Terminal Output before crash:
(firefox-bin:10099): Pango-WARNING **: failed to create cairo scaled font, expect ugly output. the offending font is 'DejaVu Serif Oblique 7.5'
Segmentation fault (Core dumped).

There is no crash report in /var/crash/, but I made (and attached) a debugging log as described in https:/ /wiki.ubuntu. com/MozillaTeam /Bugs.
Changing my font from DejaVu Serif to DejaVu Sans fixed the issue for now.
