 I am experiencing mythbackend crashes on daily basis with latest myth rpms
 from ATRPMs bleeding (mythtv-suite-0.21-159_trunk_r13460.fc6). I have been
 able to get a core file and the backtrace is below:

 Core was generated by `/usr/bin/mythbackend --daemon --logfile
 /var/log/mythtv/mythbackend.log --pidfi'.[[BR]]

 Unfortunately, 'bt full' does not contain any more information but if
 needed, I can attach the core file (it's about 270MB)
