I have had this problem for a while now (12.04 and 11.10, I can't remember if it happened before that) it has always been for the update manager, and happened nearly every time it pops up with auto updates to be installed. Strangely I just had a similar thing happen to one of my terminal window. Not sure how or why (it may be unrelated), but just thought I would throw it out there.
