This happens in response to the GPU hanging. X could perhaps handle this a little more gracefully (e.g. by reporting "GPU hung, committing suicide"), but the real issue is that the GPU is hanging on resume... Do you have a dmesg after resuming?

It'd also be worthwhile testing this out with a fresh kernel, e.g. 3.13.2, as this issue may have gotten fixed in the meanwhile.
