MythMusic SegFault

Hey all-

I updated Myth last night and now I am getting a segfault in MythMusic
when I choose "Select Music". I'm also noticing the line "playlist.o:
Not sure how I got 0 as a track number, but it ain't good" when it
starts up.

This is a RedHat 7.3 box with everything previously working fine. After
this initial crash, I updated qt to 3.1.1 (from 3.0.5) and did a
completely fresh checkout of MythMusic to see if it'd help.
Unfortunately, it didn't...

Anything else I should be trying? Any ideas???

Thanks much,
Joe

That fixed the segfault. Thanks much!

I'm still getting some fun messages...

playlist.o: Not sure how I got 0 as a track number, but it ain't good
playlist.o: Oh crap ... how did we get something with an ID of 0 on a
playlist?

Is this bad?

This is now doubly fixed.

You should get a message on your next run (from CVS) that it's removing 0's
from your playlist(s). If that keeps happening on future runs of mythmusic,
please let me know.
