Is there anything I can do to help diagnose the issue? (or should do as a workaround, alternatively.)

A couple of times, including last night.

Occasionally, and without any pattern I've been able to discern, the game hangs and then crashes on Linux. Attached is an example log.

I've been playing mostly on a server - other players haven't reported any errors, but they're on Macs.

The save game I've attached is from _right after_ the crash.
