Comment 1 Chuck Ebbert 2011-05-17 09:28:30 UTC 
There's not much that can be done here if you remove a mounted device like that.
Comment 2 Vitezslav Humpa 2011-05-17 09:38:45 UTC 
True, and it's understandable that the kernel produces an exception for this. Although, a question is whether abrt should respond on this in a "kernel crash" way.

I unmounted a 4GB Kingston DataTraveler USB memory stick. The unmount was successful, it was when I unplugged the device that I received the error. This is the first time it has happened, so I will try to reproduce it and add more specific details if it occurs again.
