Same trouble happening in 0.77.109751. Use to happen on all the dvp versions released from the beginning of august.
It happens on MP after some minutes of playing. Issue happens on most of the server I've been joining until know. Because of that, I 'm only playing on the "bellavista" server,on which I never got such a crash until now.
Using NVIDIA 320.49 driver (GTX660), Windows 7 64bits.
