Login error in dev.piwik.org

When I login in dev.piwik.org/track I have error

I use for login konqueror, firefox, google-chrome, but they all tell me about cyclic link detected. Konqueror don`t use any plugins.

We have finally upgraded Trac to the latest version and now Login + Reset password should work for all users. Please let us know if you have any problem with http://dev.piwik.org
