Thanks Isaac, I'm slowly learning...

I recompiled mythtv with the DEBUG flag uncommented in the settings.pro 
file. New gdb output is below again.

Could this be a qt library problem? I run Suse 9.0 which definitely 
caused me problems with mythmusic in the past, though the qt that I am 
running now seems to be fine with mythmusic.

Also, I had to change QMAKE_CXXFLAGS_RELEASE to have -02 rather than -03 
in order to compile in debug mode. I guess this is something with my 
compiler.

Thanks for your help,
Michelle
