gnome-power-statistics dislpays a blank window

[Pascalio]

When I open a gnome-power-statisics window (either by the icon on the top panel or by the terminal), the first time every thing works fine, but if I close the window and then reopen it (no matter how long after) the display is just blank, only the window frame and control are there but absolutely no content. I can try again as many time ever, no change. This may have to do with the fact, the process is always running in the background and the second time a window is asked for there is something wrong. If I artificially start another power statistics process, like in another account using sudo, then I can get the window to display content for the other times.
(and this has nothing to do with the presence of xfce software that appear in the addition infos, it was happening before I installed them...)

Status changed to 'Confirmed' because the bug affects multiple users.

This happens for me on a laptop with a fresh Precise Ubuntu Desktop install as well, I don't have any other *-desktop bits installed.

As an added note, killing the errant gnome-power-statistics process lets me access it correctly from the icon again (and it seems to properly close itself after that, at least, for now).

Next time this happens, I'll see if I can hunt down where the hung/sad process is coming from before I kill it. :P
