Bug#647083: gnome-shell: dependency against libgnome-desktop-3-0 instead of, libgnome-desktop-3-2 breaking upgrade path

[Pascal Obry]

I'm not sure what is wrong but I have the very same issue.

- I'm using Debian unstable
- I'm using gnome-shell from experimental

I was using gnome-shell 3.0 without problem. Then I have switched to 3.2 
to test it. The problem is that part of it was not updated, when trying 
to update to libgnome-desktop-3.2 I get:

$ apt-cache policy libgnome-desktop-3-2 gnome-desktop3-data
gnome-desktop3-data:
   Installed: 3.0.2-2
   Candidate: 3.2.1-2
   Package pin: 3.2.1-2
   Version table:
      3.2.1-2 990
         150 http://ftp.fr.debian.org/debian/ experimental/main amd64 
Packages
  *** 3.0.2-2 990
         700 http://ftp.fr.debian.org/debian/ testing/main amd64 Packages
         750 http://ftp.fr.debian.org/debian/ unstable/main amd64 Packages
         100 /var/lib/dpkg/status
libgnome-desktop-3-2:
   Installed: 3.2.1-2
   Candidate: 3.2.1-2
   Version table:
  *** 3.2.1-2 0
         150 http://ftp.fr.debian.org/debian/ experimental/main amd64 
Packages
         100 /var/lib/dpkg/status

As you can see gnome-desktop3-data is for 3.0 and 3.2 is available on 
experimental branch, but when I try to install it:

$ sudo apt-get install gnome-desktop3-data
Reading package lists... Done
Building dependency tree

The following package was automatically installed and is no longer required:
   gnome-video-effects
Use 'apt-get autoremove' to remove them.
The following packages will be REMOVED:
   cheese eog evolution evolution-exchange evolution-plugins gnome-applets
   gnome-control-center gnome-panel gnome-screensaver gnome-session
   gnome-session-fallback gnome-shell gnome-tweak-tool libevolution
   libgnome-desktop-3-0 nautilus nautilus-sendto tracker-miner-evolution
The following packages will be upgraded:
   gnome-desktop3-data
1 upgraded, 0 newly installed, 18 to remove and 35 not upgraded.

It wants to remove gnome-shell, gnome-panel...

Isn't this because of a missing/wrong dependency?

Thanks.
Pascal.
