I'd be curious to know what happened before this screen shot was taken. The coords under the mini-map are nuts, and I'm curious if the character was 'flung" way out of bounds or if it teleported there. I know the windows version had some weird situations you could find yourself in (or force yourself into) that would "fling" the character a long way, but usually put you though a loading screen that would get rid of the "momentum" and drop you somewhere playable.

Guess what I'm getting at is it might not be specific to the linux build, and might have just been a 1 in a million situation you happened to find on the linux version. The game wasn't perfect so either is possible really.
