pyrogenesis segfaults on load game

[Patrick]

Currently At revision 15536.

Across several days of pulling down revisions and clean builds I crash every time trying to load a game. Playing and saving seem to work fine, but if I try to go back in and load a game it seg-faults reliably. Here's the backtrace from the crashing thread, I haven't tried to debug it myself since I figure you might already know about it, but if you want me to, I can chase it down.
