Comment 3 for bug 1510813

There is an issue, which must be solved.

The package libgnome-desktop-3-12 forces to remove libgnome-desktop-3-10.
This in turn causes eog and libmutter0g to be removed as these have been built against libgnome-desktop-3-10.

To solve this the libgnome-desktop-3-12 must be installable alongside the libgnome-desktop-3-10.
The eog and mutter can be rebuilt against libgnome-desktop-3-12.
