gxine crashes metacity during first run

Binary package hint: gxine

I just installed gxine. The application starts and and the setup wizard dialog shows up. After clicking forward a couple of times, metacity crashes (i.e., the gnome-panel disappears, I cannot see the windows' decorations, gxine's menu doesn't work, etc.). After applying "metacity --replace" through Alt+F2, I am able to close gxine.

I suppose there's an issue with some device pointing to a non-existent location (since I get the same warning when configuring xine-ui), but I don't think it should crash metacity.

I've run gxine with Compiz disabled, and then with Compiz enabled, and it makes no difference. The nohup output follows:
