Autosave Information: Operation not permitted

I was getting the following error when trying to export to .jpg, I also tried .png and got the same issue.

The document “Untitled” could not be exported as “Untitled.jpg”. mkdir: /Users/userName/Library/Autosave Information: Operation not permitted

Using OmniGraffle 6.1.2 (v159.7 r224654) running on OS X Yosemite 10.10.2 (14C109)

The answer for me was to delete the “com.omnigroup.OmniGraffle6” folder found in, ~/Library/Containers/. Just wanted to put this somewhere on the internet because searching didn’t help me.

No idea what could have corrupted the folder, the only thing I recently did was run “Audio Hijack” and “Fission” from my downloads folder. Don’t see why that would cause an issue. FYI you will have to reenter your license information the next time OmniGraffle opens.
