if you goto http://develop.twiki.org/~twiki4/cgi-bin/oops/Bugs
which you can get if you use template login, and get an oops screen that you then login from (as template login loses the params)
you get a pretty blank, and puzzeling page.
in fact, there are 2 bugs here - as it can be caused by login losing the url params, and then redirecting the user to what becomes a bad url. same effect can be seen with the Bugs Contrib for 'create new bug'
