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:\r\n[[Image(HeadersAlreadySet.png,100%)]]\r\n\r\nUpon 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:\r\n\r\n[[Image(PleaseChangeYourPassword.png,100%)]]\r\n\r\nTraceback:\r\n{{{\r\n2012-04-03 16:43:07,069 Trac[main] ERROR: Internal Server Error:\r\nTraceback (most recent call last):\r\n  File "/usr/local/python26_trac12/lib/python2.6/site-packages/Trac-0.12.3-py2.6.egg/trac/web/main.py", line 522, in _dispatch_request\r\n    dispatcher.dispatch(req)\r\n  File "/usr/local/python26_trac12/lib/python2.6/site-packages/Trac-0.12.3-py2.6.egg/trac/web/main.py", line 269, in dispatch\r\n    self._post_process_request(req)\r\n  File "/usr/local/python26_trac12/lib/python2.6/site-packages/Trac-0.12.3-py2.6.egg/trac/web/main.py", line 365, in _post_process_request\r\n    f.post_process_request(req, *(None,)*extra_arg_count)\r\n  File "build/bdist.linux-x86_64/egg/acct_mgr/web_ui.py", line 256, in post_process_request\r\n    req.redirect(redirect_url)\r\n  File "/usr/local/python26_trac12/lib/python2.6/site-packages/Trac-0.12.3-py2.6.egg/trac/web/api.py", line 383, in redirect\r\n    self.end_headers()\r\n  File "/usr/local/python26_trac12/lib/python2.6/site-packages/Trac-0.12.3-py2.6.egg/trac/web/api.py", line 321, in end_headers\r\n    self._write = self._start_response(self._status, self._outheaders)\r\n  File "/usr/local/python26_trac12/lib/python2.6/site-packages/Trac-0.12.3-py2.6.egg/trac/web/_fcgi.py", line 1241, in start_response\r\n    assert not headers_set, 'Headers already set!'\r\nAssertionError: Headers already set!\r\n}}}	defect	closed	low	AccountManagerPlugin	normal	fixed	login password reset		0.12
