[mythtv] Mythmusic crash while scanning

[Jack R Hyde]

I have a large directory of mp3's, about 4.2k songs, and using the 
latest cvs version of mythmusic as of this writing it hangs when ever I 
try and scan the directory after starting with a fresh musicmetadata and 
musicplaylist table. It usually gets to right around 50% and hangs 
shortly after it, though some times it craps out much earlier.

I rebuilt mythmusic and mythtv with debugging and while it no longer 
complains about not having debug symbols, I can't get any debug info. 
When it crashes it just says "Cannot find user-level thread for LWP 
1824: generic error" and when I try "thread apply all bt full" it just 
says "Cannot find new threads: generic error". When I try and rerun 
mythfrontend or even just try and quit out of gdb it says "Cannot find 
thread 16384: generic error"

I assume I am doing something wrong or something is borked with my 
system, otherwise everything runs great now. Was just trying to clean up 
my mp3 tags so I zero'd the database, which is when everthing went wonky 
trying to rescan everything. If I just keep trying to run mythmusic it 
eventually finishes with everything properly scanned but trying to do it 
all at once is a no go.
