[mythtv] mythfrontend segfault except under gdb

[freedenizen]

Hi,
I'm getting a segfault when exiting almost every recording with recent
revisions of trunk.  I'm trying to get a backtrace, but when I run it
under gdb it never segfaults.  Any advice for how to get some useful
data, should I just checkout various revisions to try and pinpoint
when this started happening or is there a better way to go about this?

Thx,
Asher
