>From the report,

Description of problem:
It happened yesterday, so I think I was editing a keyboard shortcut (changing
the URL after a web browser command) and so I set the same shortcut as before.
Then a dialog popped-up asking which command I wanted to use, the old or the
new, I clicked the new one and... now I'm not quite sure if the settings
manager crashed right there
or if the window went back to the main window (that is an internal crash anyway
as it's supposed to stay in the keyboard shortcuts window).
But eventually the GUI crashed and abrt popped-up.

This is an operation that usually works, but sometimes Xfce crashes and I feel
it's related with having an old computer and doing things quickly.
Mostly is Thunar crashing when dealing with thumbnails.
