battery key tooltip won't close, cpu at 100% (gnome power manager) intrepid

[rrobe]

with today updates I read that the battery key (on my laptop Fn+F3) had been re-enabled (before pressing it didn't have any effect);

The good news is that now when I press it a tooltip shows up under by battery icon in the notification area, showing all kind of infos about it. Nice.

The bad news is that I cannot close it. When I click on the [x] icon nothing happens, the tooltip remains there.
And this is not the worse of it: my CPU goes 100% and stays at full throttle from that moment on.

This means that every time I press Fn+F3 My system becomes practically unusable (big tooltip always on top + cpu under heavy stress).

The only solution I found to get rid of the tooltip was to unplug my battery.
EDIT: even unplugging the battery the tooltip didn't close, kept refreshing itself endlessy.
The only solution appears to be a X restart.

**The problem showed up after today patches (16th of december 2008)**.

Here are some more details:
