Admin: crash when adding existing version name

[emw1989@…]

As an admin of igtd.devjavu.com, in Ticket System > Versions, I tried to add a Time value (mm/dd/yy) to an existing version entry. After clicking Save, the version was deleted (!) from the versions list, and when I tried to re-add it, I got a crash complaining about a non-unique column name.

Thanks for any help!
