Bug Description
Binary package hint: mythtv
Public bug reported:
Binary package hint: mythtv
Myth frontend crashes when switching between iptv channels when watching live TV. The
backend is located on another computer running ubuntu 9.04 with
mythbuntu ppa. The frontend is mythtv from standard ubuntu karmic.
The bug was reported earlier as #482595 but was marked as invalid because of incomplete bug report.
I didn't manage to get any info from apport so I created a backtrace using gdb instead, now with proper symbols from mythtv-dbg.

Howdy, and thank you for going the extra mile to get a valid backtrace. I went ahead and opened an upstream ticket, but you should be aware that you, or your mirror, does not seem to be tracking the auto-build ppa correctly - the mythtv revision for fixes is well about the 23000 number now. It is remotely possible this problem has already been fixed. If you can update and report back, it would be greatly appreciated!
