Bug Description

Binary package hint: indicator-sound

Going through the USB sound checkbox test and had the Sound Preferences window open.
Unplugging the USB device while the window was open caused volume indicator to appear as if the output was muted and a the application crash notification appeared with prompts to report the bug.
Changing output volume had no effect on the "indicator-sound".
Audio is functional, I can change volume, the OSD notification appears, but the volume indicator in the top menu bar does not change, it continues to sugges that the output volume is muted.

The speakerphone was a ClearOne Chat 50 in case the submitted files don't have the USB device information.

This is a duplicate of 522428 (cannot mark as a duplicate for some reason). Honestly it seems like an odd bug. Its like the info pointer in the update callback has become Null just as the callback has been triggered. The fix is to make the update code safer at this point. Will keep an eye on this.

I have not been able to reproduce from my end (which is annoying).
Please retest with indicator-sound-0.2.2
