Comment 5 for bug 1255791

Fixed in r12911. I've added 5 letters, 'break' ;-)

Basically the switch case for the event handler has the mouse release event gate crashing into the enter notify event. Causing all sorts of nasty.

The problem is intermittent, so I've just been creating and deleting 45 guides without a crash. Before the longest line of non-crashing was 7 and most within 3. Please test your versions and report if you spot a crash after 12911.
