Comment 5 for bug 386507

okay, again 2 issues here. The "Error window" is because fontconfig support was not enabled. fontconfig enables mplayer to detect the "default system font" automatically. It is not enabled by default, users need to enable it with the commandline switch -fontconfig. We can fix the desktop file to call mplayer with -fontconfig by default. This should be tracked seperately.

the original report mentioned in the bug description is a problem in the interaction between the mplayer-skins and the mplayer-skin-blue package. The mplayer-skin-blue manages the //usr/share/mplayer/skins/default symlink via update-alternatives, while mplayer-skins does fiddle with the symlink manually. This is plain wrong of course.

I'd suggest to just merge the mplayer-skins package with the mplayer-skin-blue one.
