Yes. I'll write some more tests and commit it in time for the 2.12.5 
release. Thanks for catching this issue early enough!

An other advantage of the re-raising pattern is the fact that you can 
easily change the response type by raising a different exception inside 
the view. I plan to use that for replacing the nasty unauth redirect 
code in CookieCrumbler. The exception view will raise Redirect or 
Forbidden if you are already logged in.

Yes. Perhaps ;)
