We do use notify_close_if_showing() to hide any non-relevent messages when we show a new message. Can you give an example where we show more that one power notification messages at one time? Thanks.

Bug 687658 is an example, no?

Here is an example:

I just got a 'battery critical' notification and scrambled to plug in. Now my battery is happily charing, but this big, scary, red battery icon is sitting in my message tray. It should be removed as soon as I plug in.

Debug message now slightly misleading...

Just saw this on F19/GNOME 3.8.2 - three low power warnings, all in a row.

File a new bug please.
