9942,'Headers Already Set' error after password reset,rjollos,hasienda,"I'm running the latest version of the AccountManagerPlugin, r11364, and Trac 0.12.3. After creating a user account and logging in as that user (to work around #9252 / #9843), I reset the users password to force them to change it on first login. When the users logs in, they see the following error:
[[Image(HeadersAlreadySet.png,100%)]]

Upon attempting navigate to any other page, they are redirected to the ''Change password'' page and prevented from accessing any other page before changing their password:
