This is an interesting little bug. Seems like the code I had to catch this state was automatically compiled out by valac. Re-doing the function puts the checks in place and will now guard against this.

Opening again. We have not reproduced this properly, and want to make absolutely sure it's sqashed good, before it's dropped off the radar.

Won't fix for Maverick, as there is no documented way to reproduce it and really nail it down quickly.
