[mythtv] MythMusic crashes scanning for music BT included

I've got an issue with MythMusic 0.10 when 'scanning for music' and have
included a backtrace below in case it's any help.

It's always repeatable for me and _doesn't_ seem to be related to the
actual mp3s it's scanning (I've moved directories out the way to check).

I should add this is over NFS and it seems to manage to import the first
few directories and crashes after the first 2 or 3 directories have been
scanned. There's not an unusual amount of files in any of the dirs, just
the normal number of tracks from a CD.

Without the NFS mounts, it seems to work ok on the local filesystem when
scanning. I've given the NFS a good thrashing itself and that doesn't
seem to be a problem.

Any help?  I'm currently doing a debug compile in case that would be 
more helpful.
