This affects me aswell, and has done since I upgraded to Karmic. On my machine it is only triggered by mail-notification when I receive a new mail, so an educated guess would (of course) be that it is triggered when mail-notification tries to show a popup (that I never have a chance to see, since notify-osd crashes).
