gnome-power-manager hang in Precise Beta 2

[Manish-Raj]

I was viewing the power statistics using gnome-power-manager. When I clicked on Processor side-tab , It freezed. There was no response on clicking any button. Maxiimize button was working but was just maximising the window. On minimising the window and reverting it , the content were gone. There was just a window with no content. Close button was not at all working.
