pcbnew crashes on OSX when exiting zone settings dialog

[Christoph Nieß]

When changing an existing zone, roughly every fourth try, pcbnew will crash while redrawing the zone after pressing OK. It is not necessary to change any zone setting, just opening the dialog and hitting OK is enough.

OSX crash report is attached.

To make things easier, the pcb file I encountered this one with might help...

I cannot duplicate this on Linux so it may be MacOS only.

My coworker just had a crash when changing the priority of a zone. He has probably done this on ~50 zones, but only last one crashed.

Im not sure if this is the same bug, bug I'm asking here before posting a seperate bug.

Weird thing is he is running linux.

It is possible that this could affect Linux, just not as easily/often. Unfortunately, I can't make out much from the stack trace. Can your coworker run a 5.1 nightly? Or let us know if it happens in 5.1.1. If it does, then we are different.
