stonesense: sigsegv on exit

[ewtoombs]

When stonesense is running and DF is closed, I get a segmentation fault with the following backtrace:

I've been trying to recover a core file, but ulimit -c 1 doesn't seem to have any effect. I am running libx11 1.6.2 and sdl 1.2.15.

This only happens when I run stonesense, so I am tentatively calling this a bug in stonesense. Anyway, see if you can reproduce it. All I had to do was

1. Run dfhack.
2. Run stonesense from the dfhack console while DF was still in the menu.
3. Close DF by hitting 'Quit' in the menu.

PS: I generated a core file, but it's 300 megs, which is obviously far too big to post here. If you really need it, I'll find a way.
