media-plugins/xmms-kde-3.1 wants arts to be emerged eventhough USE="-arts" is set.
xmms-kde just needs arts, if you don't have it you cannot use this app. That makes this bug invalid i think.
I am using xmms with alsa and whereas xmms-kde offers a small dock control. I can't see the use for arts. But ok, that's project specific.
It required arts, not a bug. There's also no arts USE flag in xmms-kde ebuild. [ebuild N ] media-plugins/xmms-kde-3.1 USE="-debug sdl xinerama -xmms" 1,067 kB
