I was trying to run titi's benchmark scenario on r2554. So I loaded it, and while everything loaded fine, and I got to see the in-game screen with objects rendered, the game ran into a segmentation fault:
Core was generated by `./megaglest'.
Program terminated with signal 11, Segmentation fault.

I did the exact same thing again a few minutes later but not not reproduce it then.
