Do you have on-demand patching turned on? If so try creating the map again. We were getting this bug on tribble where it would crash if you hadn't downloaded the map before. It would be a little disappointing if this bug hadn't been squashed, considering that it was reported months ago.
If you had on-demand patching disabled, then it would be a new problem.
It should be fine regardless after that first crash. The problem is with the first time it tries to download (or that's what I think it is, keep in mind I'm not a dev). But yeah you might consider disabling on-demand patching, otherwise you might get this same crash with some of the other maps.
