You do not have to reboot the machine every time it happens! Use the
System Monitor Gnome Applet to kill what ever is using it.

Further more this really seems like a Bug in the way Applications handle
killing processes. Why? I have a Client this happens to often. Exactly
the way you describe.

One idea why it affects my clients machine is it is running 4.7 and is
dog dead slow. Wait 5 minutes and the processes finally exits. In theory
it should exit when the app is closed.
