Do you have multiple monitors, or are you disconnecting the only connected monitor?

OK, then this is a known issue - we currently don't support running with no monitors connected. You'll get different backtraces depending on which version you use, whether you start with no monitors or disconnect it later, or whether there are open windows at the time or not, but it all boils down to that underlying issue. It's tracked in bug 730551, though I'm afraid the bug has been stalling for quite some time :-( *** This bug has been marked as a duplicate of bug 730551 ***
