Affects: gnome-panel (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
This happened on both a Breezy as a Dapper machine. It's reproducible but not through a serie of steps; it just happens once in while.
It's a bit hard to tell what happens, but the screenshot should explain it.
