Error reprocessing in Paperclip 2.3.5

Question

I updated from 2.3.3 to 2.3.5 for the string to array bug, and now when I try to call Model.image.reprocess! I get the following error. Is this something in my code or something in paperclip? Or maybe in the image I'm uploading?

It's a bug with paperclip. Revert to the previous version and you'll be fine. This really had me pulling my hair out for a few days as well. :)
