IntegrityError: duplicate key violates unique constraint "session_pk"

[anonymous]

I tried to find the outstanding issues on 0.11 by reporting by version. I probably clicked the link more than once: it didn't seem like it was responding and I'm impatient.

How to Reproduce

While doing a GET operation on /report/5, Trac issued an internal error.

(please provide additional details here)

Request parameters:

{'id': u'5'}
