Comment 5 for bug 441686

The question in the above comment has been "voluntarily removed by its author", but I too am seeing the problem.

I am running Natty (upgraded through the last few releases I think). I just ran update manager and got this dialog. On my system, the GUI is frozen as a result. I am able to move the mouse, but nothing on the screen responds to a mouse click. The clock is also not updating. The system is not frozen as I am able to ssh in to try to diagnose the problem.

I'm leaving it with the error up for a few mins if anyone wants me to check anything.
