[Rhythmbox-devel] encountered a crash when playlist managing

[Andreas Fuchs <asf boinkor net>]

Hi all,

I have managed to get a backtrace from a crash. Not the one I whined
about on IRC, but that's only a matter of time. (-:

This one happened thus: I played a song, dragged another to a fresh
play list (this one I created in an old rhythmbox instance, i.e. it was
already saved, but empty), then I changed to the playlist and used the
context menu to "delete" the song from the playlist -> crash.

here's a full backtrace:

Hope it's useful to you guys. Thanks for hacking rhythmbox - I'm very
glad that it's somebody's goal to make a usable (as opposed to "just
pretty") music player for linux.

If you need further information, please ask. I'll leave this gdb
instance running in case you do. But please Cc: me on replies, as I'm
not on the rhythmbox list; I set Mail-Followup-To to comply.

Thanks,
