[mythtv] Mythfrontend Crashes

Thu Feb 10 19:46:13 UTC 2005

  I've been seeing periodic crashing of Mythfrontend on
my box for the last couple weeks. 

It seems to only crash under a specific circumstance, but it's not
consistantly reproducable.

Basically each crash has occured after several hours of
the interface idling with "Watch TV" highlighted. I highlight
Watch Recordings and as soon as I press enter it crashes.
I updated to the latest CVS last night and grabbed the following 
backtrace this morning when it crashed. Is this something Myth related?
