Here it is.  The assertion failure still happens with the last patch applied
(and debugging enabled), so I guess it's a separate issue.

Seems a bit random; sometimes it crashes instantly as soon as I start the
server, other times it crashes when I start interacting with things,
sometimes it doesn't seem to want to crash at all.

This log came from a run where it crashed as soon as I tried to interact
with the gmpc window.
