Public bug reported:
I suspended the laptop and unplugged the external hard drive USB cable
while the laptop was still suspended. Resumed the computer, played some
music in the lastfm QT client and stopped it, then tried to open a
nautilus window to unmount a USB flash drive, then the oops happened. It
seems unplugging the drive while the computer was suspended caused this.
No programs were reading or writing anything to the external drive
before I suspended the computer, excluding background system tasks or
Nautilus.
