XBMC Constantly Crashing

Hi Guys

I'm pulling what littler hair I have left out trying to find a solution.
It seems that everyday when I return to my pc I come back to a crashed XBMC

I have no idea why. I can usually troubleshoot pretty well but the log file isn't giving me any clues, none that I understand

Any help at all would be great - Log file is here: http://pastebin.com/iCThV2tx

Thanks
