IntegrityError: duplicate key value violates unique constraint "session_attribute_pk"

How to Reproduce

While doing a GET operation on /report/7, Trac issued an internal error.

I created a new account, logged in, send a ticket and I wanted to see "My ticket" page to check my patch submission was okay. I get this error instead.

Request parameters:

{'id': u'7'}

[titer]

We upgraded Trac to 0.12 stable - is the error still happening?

I'm not able to trigger the error message for report 7, either when logged in or logged out, and the OP hasn't reported back, so I'm going to assume titer's upgrade to trac 0.12 fixed the problem.

stephane: If this problem persists, please reopen this ticket. Thanks!
