Crash when hitting 'cancel' button from Brasero's nautilus extension "Write to Disc" dialog
I've twice managed to crash gnome-shell by just hitting the 'cancel' button in the "Write to Disc" dialog you can get by installing brasero-nautilus, right-clicking on an ISO file, and selecting "Write to Disc". It doesn't happen every time, but after it happened by accident the first time on my desktop, I tried testing in a VM, and got it to happen on the third or fourth try.
I will attach the backtrace.
