Deploying the spinning cube example to iOS (Mono) and attaching the script debugger crashes to XCode. Script debugging not possible.

To reproduce:
Open project (either v4 or v5 depending on unity)
Set build target to iOS
Set Development Build on
Set script debugging on
Open Spinning Script file, set a breakpoint and attach script to your device via cable or WIFI.
Optain either crash in XCode (see image) or you are not able to connect to profiler anyway (see image) normally it's not possible to connect to profiler after app crashed once.

Reproduced on 5.0.1p3, doesn't reproduce on 4.6, since mono freezes when trying to attach to process
