Comment 16 for bug 1067265

I can confirm the issue being related to something empathy does, in particular I noticed it happening when resuming from suspend:
- I get some automated messages from nickserv and channel bots, the icons indicates two messages per channel
- if I right click on the icon and select "remove", another "ping" sound is played, the second message pops up from the tray and the tray disappear.

Sometimes I had an even stranger behaviour: by doing the above actions while in overview mode, notification area moved up to about 1/4 of the screen, like if the pop up animation was triggered again while the bar was already visible.

I'm using Ubuntu 12.10 with -proposed repository enabled.
