The default skin (Blue-1.6) has been packaged rather sloppy and contains a .svn directory which shouldn't be installed. use gtk && unpack Blue-${BLUV}.tar.bz2 && rm -rf Blue/.svn
Forgot the icons directory use gtk && unpack Blue-${BLUV}.tar.bz2 && rm -rf Blue/.svn Blue/icons/.svn
Please send an email on the mplayer-user ml.
Upstream has fixed the issue and repackaged the skin. The digest will need an update.
