Bug description:
[Impact]
Crasher related to device mounting handling
[SRU TESTCASE]
1) Attach an USB stick to your computer
2) Click on the USB device launcher icon so that it gets mounted
3) Right click on the USB icon and click "Umount"
What should happen:
4) The usb stick is unmounted (the icon is removed from the launcher)
with no unity crashes.
[Regression potential]
Test the testcase and volume handling in general, shouldn't affect
anything else.
---------------------
I can find a existing bug report. I get this crash after a restart of
the system.
