Comment 22 for bug 1512002

I'm pretty sure the message notification panel is to blame. I ran with it disabled for several days a few weeks ago and I wasn't plagued by this dialog on a single occasion. Unfortunately, though I can do without the notifications, I can't do without the volume control and for some bizarre reason they are one and the same :/

If a few people could confirm that they see this behaviour disappear when they unload the notification panel, at least someone could start taking a look at the code/config that might be the cause of this annoyance.
