Comment 11 for bug 660833

Same issue here, although I'm no longer certain the problem is with mythtv itself. I've had this crash occur at least once while looking through the system settings from the desktop without mythfrontend running, once while in the mythfrontend settings, as well as several times during playback. It is only when the crash occurs during playback that I see a general protection fault against the mythfrontend,

I cannot reproduce this issue reliably, however in general it appears to happen about once every 60-90 minutes after a clean start, although it will repeat more often than that if I log back in but do not restart after the first crash.

In the case where the crash (back to the login screen) occurred while in the mythfrontend settings, syslog included "Nov 14 14:08:17 myth-tv init: mythtv-backend main process (1829) killed by TERM signal"

In the case where it crashes during playback, dmesg includes:
"[14753.621610] mythfrontend.re[11752] general protection ip:7f658c163445 sp:7f656cad5020 error:0 in libc-2.12.1.so[7f658c12a000+17a000]"
and mythfrontend.log includes:
∘ <unknown>: Fatal IO error 104 (Connection reset by peer) on X server :0.0.
∘ <unknown>: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0.

I've tried disabling XvMC by removing /etc/X11/XvMCConfig to no effect.
I've tried switching to the "nv" driver, however X then fails to start at a resolution supported by my TV (46" LCD), so this doesn't appear to be a usable workaround for me.
