Blank gnome window after upgrading Lenny to Testing

[S Scharf <ss11223@gmail.com>]

Now that OO.org 3 is in testing, I upgraded my system from Lenny to
Testing.

When I log into gnome (or safe-gnome) from gdm, I now get a window
with my wallpaper and NOTHING ELSE. No mouse clicks bring up any menus.

(Logging in with KDE looks like it is working)

Any Ideas on what file is broken?

Thanks,
Stuart
