How can I interpret the last exception file?

Don't suppose anyone can help? I get a last exception notification whenever I try to use an art easel. Have gone through and deleted bad cc and updated my mods (I think!) and have tried the 50/50 method but everything works fine until I put everything back and try to play. It doesn't cause any game errors - nothing freezes or anything, I just get those annoying orange notifications from MCCC (and can't figure out a way to turn them off!?)

The text from the last exception file is this:
