mythfrontend.real crashed with SIGSEGV in QX11PixmapData::x11ConvertToDefaultDepth()

[Ryan Olf]

Binary package hint: mythtv

Upgraded from Mythbuntu/Ubuntu 9.10 via Ubuntu automatic upgrade UI. Mythfrontend now crashes almost immediately on boot, although if I change the theme to Terra, it actually works. Arclight and mythbuntu themes crash. I may try a clean install, but that would be annoying. Rebooting computer and reinstalling the frontend doesn't seem to help.

Howdy, and thank you for helping to improve Mythbuntu by opening this ticket. Could you please update and report back if this still occur after 0.23-fixes24311 (which is now available on auto-builds)? If you need help enabling auto-builds, please see http://www.mythbuntu.org/auto-builds.

Bug #560889 is likely a duplicate of this one.

Almost certainly a dup of #549593 (which also describes 560889)
