I can also confirm this problem on Squeeze. I only encounter the misplaced popup the first time that the toolbar menu is accessed, and only on the title popup menu of the toolbar. On subsequent times, the menu appears in the correct position.
It only appears to happen when the toolbar placement is at the bottom or the right of the screen. The initial menu position is set to be below and to the right of the mouse position, so the failure to correctly position the menu is not as obvious for other toolbar placements.
