I goofed at login, and hit the "eMail password" button with all the fields blank. I then enterd my eMail and his "email password" again. Worked fine. Then hit back, entered password, and pressed login. "Password emailed". Maybe I hit the wrong button, so I hit back again and then hit login. Same effect. Hit back, re-entered password (in case I mistyped), hit login. Same effect. Hit back TWICE and then entered email and password. Login worked.
When I click on the Email Password with the login name field blank I get an error message the the email address (same as login name) did not pass minimal syntaxt checking so therefore I am not able to replicate the mentioned problem with the latest Bugzilla code. Closing.
