According to all information I can find, this:
2013-11-22 12:02:49.893 mplayer[55046:f0b] *** Assertion failure in -[NSWindow _changeJustMain],
2013-11-22 12:02:49.894 mplayer[55046:f0b] An uncaught exception was raised
2013-11-22 12:02:49.894 mplayer[55046:f0b] Invalid parameter not satisfying: [self canBecomeMainWindow]

Is a bug in Apple's code.
We could catch the exception or try some other workaround, but in principle I'd
say Apple needs to fix their code.
