9591	segmentation fault in qt on play in mythmusic.	hcoin@…	paulh	"Mythmusic crashes with a segmentation fault every time, just at the moment playback begin is attempted.  Navigation route: Launch mythfrontend at the keyboard, attempt to play using 'all my music', navigating to a single music file, hit 'enter' and crash-- back to a command prompt and the end of mythfrontend.   Tried classic and ubuntu themes, same result.  System has a couple of dual ported video cards with monitors attached to each.

TV recordings at both SD  & HD , dvd/video playback all normal.   Output is digital spdif/iec on an ICH5 chip.  Rhythmbox plays the same music library without problem on the same system out the digital port.

System is Debian Squeeze, qt4, kernel 2.6.32-6-686  and all the mythfrontend terminal and gdb reports, including stack backtrace details are here:

The clip right around the fault report is:

I've reinstalled qt4, removed as much of qt3 as I could, thought it was an ALSA thing for a bit having to do with upconverting 44.1 cd flac file to 48K for the ICH5, but if that's so why would all the other music programs work playing back the same file w/alsa?  So, out of clues.  Posted on the user's list, no responses.  

Thanks!
