Upstream has not been able to reproduce this in MythTV 0.23, so it is presumed fixed. If this still affects you after you upgrade to 0.23, please feel free to open a new ticket and attach a new backtrace. Note that the backtrace generated by the default ubuntu mythtv package is usually not usable (all symbols are missing) - you may need to installed mythtv-dbg and mythplugins-dbg
