Trying to load the page /wiki/restricted gets me this error:

AttributeError: 'NoneType' object has no attribute 'has_permission'

Error Log reports:

Using Trac 0.10.2

Thanks for your bug report. Unfortunately I can only recommend you to upgrade to the latest Trac version 0.10.3.

I've looked into the problem but can't find the actual cause for it. Obviously in Trac 0.10.2 the Request object req which is being passed to my IRequestFilter method pre_process_request doesn't have the perm field set appropriately. As I'm using the has_permission method of perm, the reported error occurs. I'm not really sure wether this was a Trac bug in 0.10.2 that somehow got fixed in 0.10.3 or wether I'm doing something wrong in the plugin. For the moment I'm assuming the former. If somebody reading this knows the cause, then I'd appreciate to hear it!

I've added a clear error message in r1928 for users that have this problem.

Had this in trac 0.10.3, fixed it by upgrading the Web Admin plugin to 0.1.2.4429 (current freebsd port version)
