Comment 349 for bug 439448

I have two manifestations across 3 i386 Maverick machines, two from fresh live cd install, one upgraded from Lucid. Installs from 8th Jan 2011 to 10th Jan 2011, all updated on 12th Jan 2011.

Manifestation One.
The top panel appears and looks ok but cannot be accessed when left clicking with the mouse, i.e. no menus or flying hints appear. Bug is intermittent. Some start ups are fine then after a day or so the manifestation reappears.

Manifestation Two.
The top panel icons are incorrectly presented with no Applications, Places, System visible and the Indicator Applet Session duplicated and overlapping such that the Shut Down menu doesn't show. To the inexperienced user there is no way to shut down the machine other than the power button with a fair chance of corrupting the system in the process. This manifestation is equally intermittent.

This should be of high importance as data loss is possible upon enforced power button shut down. Reporters should be encouraged to report all behaviour until the bug is fixed. Clearly (or it would be fixed) we do not know enough about it yet. Please remove the discouraging sticky.
