Bug Description
Binary package hint: network-manager
When I click on the NetworkManager icon sitting on the notification area, I get a list of the available WiFi access points. When this menu is open, nm and X uses up to 100% CPU, as the attached image shows.
I think the problem is related to the progress bars. Each access point has a "progress bar" displaying the signal strength. These bars are animated in the Human (Murrine-based) theme, and I suppose, that the animation of each bar can cause the abnormal CPU activity.
I think the progress bars should not (and need not) contain animation, because they does not "express" any kind of "progress" (as in file copying).

I would like to add, that if there is >20 wlan access point in the reach and you have a small screen (netbook), you just cannot browse because of the extra CPU activity. Scrolling just about 10 pixels up takes 2-3 seconds, so this bug renders almost useless the whole access point list.
