From the Debian mailing list: Multiple people seem to have this issue, including me. The problem is solved in gnome-shell from unstable, you can either wait until it migrates to testing (in 1 or 2 days I guess, judging from the QA page [1]) or you can install from unstable with "aptitude install -t unstable gnome-shell" (no quotes). Make sure you have unstable in your sources.list file. Just be careful not to upgrade your whole system to unstable, but only that package. It worked for me!

The aptosid.com forums are also useful for researching debian testing or unstable breakage. Good luck - as a user of debian testing and unstable I've been there before.
