How to Reproduce

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

(please provide additional details here) Appears to be related to cookies, as the error does not occur if cookies are cleared. However, obviously, this also removes any active sessions. Tested in Firefox 3.6, IE 8 and Chrome 4.1.249.

Request parameters:

{'id': u'7'}
