Segfault entering a lab.

[Griffinhart]

Version: 0.B-1775-gca14431
Built on Win 7 Pro x64, Cygwin x86.

Tried to enter a lab (don't think it was ice; if it was, the temperature drop at the surface wasn't noticeable through my character's clothing), segfault occurred after the new level loaded in.

I'll try and get a save file; I hadn't saved in a while when the crash occurred. Grumble

Looks like the same bug as we were hitting in #10580. >_< Leaving it open for the backtrace, thanks.

Should have been fixed, regardless not enough information to pinpoint the exact cause.
The proximate cause is an invalid item iterator, but the actual cause is whatever invalidated it.
