The last two have you save a screenshot a few times a second, so perhaps that is overloading it somehow. Check whether your F12 key is stuck down as it is the key that saves a screenshot.
The third-to-last log doesn't seem to have a crash, and the last two are truncated. All these logs are a bit too much. Could you reproduce the crash and then post that log? Otherwise, I'm not going to search though all these logs for ones with a crash.
