gnome-volume-control crashed with SIGABRT in raise()

[Rachel Greenham]

Binary package hint: gnome-media

Audio device is an iMic connected to normal speakers.

I'd applied updates to bring me up to date as of a few minutes ago, logged out and logged in again. Next time I tried to play a youtube video, no sound. look at sound prefs; the iMic is not showing in the Output tab. In the Hardware tab it *is* showing, but when I click on it, then click on "Test speakers". After a few seconds this error occurs. (The Test Speakers window does not open.)

I used to get this more frequently (albeit at the time with a different USB audio device (Asus UBoom-Q); but hadn't encountered it for a while. I think back then I didn't get a "Report Problem" dialog, whereas, because I got one this time, I clicked it. :-)

Usually then doing a 'killall pulseaudio' would make everything all right, and I'll try that right after submitting this bug (not sure if it might otherwise interfere with files apport uploads).

This is probably hard to repeat; beforehand I would only get this sporadically, and this is the first time I've had it again recently.

confirmed killall pulseaudio still clears the problem, though needed to restart browser to get sound from that.
