More info:

line 2226 in gmain.c is

      if (pollrec->fd->events)

Comment 2 David Schleef 2004-04-15 23:20:49 UTC

Allegedly, this is due to deleted files in rhythmdb.xml.

Still segfaults, even after patch-245.

Comment 3 David Schleef 2004-04-15 23:58:59 UTC

new backtrace, with patch-245

Comment 4 Colin Walters 2004-04-16 00:42:41 UTC

* committed rhythmbox-devel@gnome.org--2004/rhythmbox--main--0.7--patch-247

Thanks for helping to debug - this was a really nasty one.  We were definitely
talking to GTK+ in the RhythmDB thread (a big no-no).
