Comment 1 for bug 144951

I have exactly the same problem on my Compaq nx7010 notebook running Feisty Fawn. Not using gutsy though.
The thing is, when I add a new user, I don't have this problem when logging off from this new user.
So I replicated this new user's home dir with permissions and all (knowing what I'm doing) without effect.

I don't have the time now to sort this out so I guess re-installing is the only way to go right now. If this happens again after re-installing, I will pay special attention to what I did just before the problem arose, in order to find a possible cause.
