Kerbal Space Program

The Part.OnDestroy method seems to have a C# error. Under certain conditions a UnityEngine.Collider List is modified (an element is deleted, added, or the list is cleared) while enumerating the list; this is a common and well known C# problem. The error causes an invalid operation exception and interrupts the Part.OnDestroy method.

This can be easily and repeatably be triggered.

Steps:
1: Create and launch a new vessel, it doesn't matter if the vessel is left on the launch pad or landed on Minmus, this can be done anywhere.
2: Take a Kerbal out on EVA.
3: Do something to make the Kerbal fall down (ie trigger the rag doll animation); on the launch pad this can be done by either climbing on top of and jumping off of a command pod, or by diving off the edge of the launch pad, on a low gravity moon the jet pack can be used to crash into the surface or vessel.
4: Return to the command pod and re-board.
5: The following error message will be displayed in the debug log:

InvalidOperationException: Collection was modified; enumeration operation may not execute.
        at System.Collections.Generic.List`1+Enumerator[UnityEngine.Collider].VerifyState () [0x00000] in <filename unknown>:0 
        at System.Collections.Generic.List`1+Enumerator[UnityEngine.Collider].MoveNext () [0x00000] in <filename unknown>:0 
        at Part.OnDestroy () [0x00000] in <filename unknown>:0

The included output_log file displays this error twice, triggered on Minmus and on the launch pad, on lines 10701 and 11035.

The save file was used to generate the log file and the Minmus landing craft is included, the launch pad craft is a Mk1-2 command pod by itself.
