ConcurrencyModificationException while editing or adding comment
Kelly Rubrecht was getting a ConcurrencyModificationException when trying to add/edit a comment or edit and entry that had a hidden comment made by someone else but with hersel tagged as the coauthor. I emulated her user and was able to recreate the problem. Logging in as myself with super admin privileges, I did not see the problem. After I removed Kelly as a coauthor on the hidden comment, the problem went away.
