Bug#749315: gnome-shell: Workspaces seem broken

[Anthony Bourguignon]

Hi,

I have resolved this issue. I realized that the problem occured only
when I was using an external screen. It worked perfectly when I was
working on the built-in one.

So I tried to change a few things in the control-center and I had error
messages.

So I checked the version of gnome-control-center : 3.8.3. I've updated
it to 3.12 from experimental and everything works damn fine now.

I think you should put a dependency between gnome-shell 3.12 and
gnome-control-center 3.12 to avoid this kind of issues.

According to me, you can close this bug.

Thanks a lot.
