How to Reproduce

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

(please provide additional details here)

This is with bitten 0.6dev-r502. Don't know if its a bitten or a trac issue.

[osimons <simon-code@…>]

This is a Bitten issue - the code does not make available the required req object for checking permissions needed for current Trac 0.11dev.

Without knowing the details of this project at all, it is quite possible that this code won't get updated before the TracDev/ContextRefactoring is settled and implemented…

Closing this ticket, and please file the ticket with the Bitten project.
