[1.2.5] os/x crash in particles thread

[Doctornull]

I was resting when the engine crashed, so maybe it had something to do with a crystal's teleportation?

Second time the particle system has crashed in the Scintillating Caverns.

Stack dump appended to log file.

Happened again, this time leaving an empty level of the Scintillating Caverns.
