[mythtv-users] Segfaults (with backtrace goodness)

Sat May 13 15:26:34 EDT 2006

Periodically mythfrontend just disappears, always (so far) during playback 
or while paused.  It doesn't seem to be related to anything (it can happen 
almost instantly, or after many hours) but I can reproduce just by hitting 
'pause' and going to bed.

Nothing else ever fails (memtest86 ran overnight without issue and I already 
pulled and returned the bad drives) so I don't think its hardware-related.

Running (from atrpms) 0.19-128, on a dual-core amd64 (smp kernel, 32bit 
kernel/userspace) with a fanless geforce 6600 pci-express (yay woot).

If there is more info I should supply let me know. Package versions at the 
bottom.

Here's the backtrace:
