--- Comment #2 from Nicolai Hähnle nhaehnle@gmail.com --- Thanks for the report, but to be honest, the backtrace looks like this is a game bug. The last function on the stack belongs to the game, and then it jumps to 0. This is what you would see if a game doesn't properly check extension support, for example.
