[ubuntu-mono] [Bug 117726] Re: [gutsy] muine crashes on adding music to the playlist

[Peter Adolphs]

I get the following (slightly different) error messages with muine
0.8.7-1.1ubuntu2 on gutsy when pressing the "Play Album" button:

---------------------------------------------------------------------------------------------------------
[several Gtk-CRITICAL messages removed]

The bug always appears when you press "Play Song" or "Play Album",
making muine unusable in gutsy.

The bug is gone with a self-compiled muine-0.8.8.
