[PATCH] login, logout redirect breaks with an AttributeError

[Jeff Hammel]

Following successful login, I get the following error on redirect:

 Trac detected an internal error:

AttributeError: startswith

My setup is:

• trac trunk, r7338
• accountmanager trunk, r4116 (using htdigest and form authentication)
• tracforge 0.11, r4116

This seems to be because the request is being passed in to a method bound to the request (old_redirect is a bound method). This can be fixed with the following patch:
