Bugzilla Bug 85552

Something is broken with USE flags in latest totem ebuild, when using 
gstreamer backend. It tries to emerge gst-plugins-a52dec as a dependancy,
even though USE flags are set to "-a52" (xemerge is an alias for 'ACCEPT_KEYWORDS="~x86" emerge').

# xemerge totem -pvt

These are the packages that I would merge, in reverse order:

Calculating dependencies ...done!
[ebuild     U ] media-video/totem-1.0 [0.101] -a52 -debug +dvd +flac +gnome -lirc +mad +mpeg -ogg +oggvorbis +theora -xine 1,369 kB

[ebuild  N    ]  media-plugins/gst-plugins-pango-0.8.8  0 kB
[ebuild     U ]  media-plugins/gst-plugins-theora-0.8.8 [0.8.2] 0 kB
[ebuild  N    ]  media-plugins/gst-plugins-dvdread-0.8.8  0 kB
[ebuild  N    ]   media-libs/libdvdread-0.9.4-r1  -static 257 kB
[ebuild  N    ]  media-plugins/gst-plugins-a52dec-0.8.8  0 kB
[ebuild  N    ]   media-libs/a52dec-0.7.4-r3  -debug -djbfft 

When using xine-lib backend, everything seems to be fine.

Reproducible: Always
Steps to Reproduce:
1. Unmask totem-1.0 ebuild
2. Make sure that 'a52' USE flag is off
3. emerge totem
Actual Results:  
pulls a52 related packages as a dependancy

Expected Results:  
don't install unnecessary packages

totem has gst-plugins-a52dec as a dependancy if you have the "a52" _and/or_ the
"dvd" use flags.

this is the intended behaviour, dvd often use ac3 audio which is handled by the
a52 plugin.
