post_process_request sent a None argument

Ubuntu 11.04 trac 0.11

I am sorry but I am new and this is what I know now, what other things are needed to answer this problem.

Having a similar problem - everything was working fine, until I installed http://trac-hacks.org/wiki/TimingAndEstimationPlugin. After creating a ticket, can't go into it anymore (says TIME_ADMIN is required, although my user has TRAC_ADMIN), and the same error is in the log.
