Comment 12 for bug 822672

This bug seems to have returned, or else its cousin has arrived on the scene. See the attached screenshot taken while applying updates today. Note: to make sure it was not due to a compiz crash that had occurred, and that it wasn't fixed by the latest updates, I ran apt-get update again, resulting in the big black square in the screenshot.
(It seems I can only do one attachment, and I don't want to start spamming inboxes, so I'm only including last screenshot. I have another with a giant grey 'package manager working' icon the size of the black box, another with a regular-sized orange 'updates ready' icon that appears about 2 cm below the panel, and another with a 'restart required' icon about twice the usual size.)
