 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!
