Hello,

We are now getting following error on one of our projects:

This occurs on every build attempt. Resetting the repository didn't affect this.

Hi Olli   
  
 One of our guys saw this issue on his dev machine today, of course when we tried to debug it, it worked fine and we were not able to reproduce it. Try restarting the agent. We’ll take another look at this.

Hi Olli   
  
 We spent some time on this today, and think we may have fixed this issue, unfortunately we were not able to reproduce the problem, so I’m not 100% certain it’s resolved. I just uploaded a new build with the fix we put in today.
