User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0 Iceweasel/30.0 (Beta/Release) Build ID: 20140614071913 Steps to reproduce: I am trying to change my account's email address to firstname.lastname@example.org. But I have an old account with that address. So I changed that old account's address to one of my other addresses. But when I try to change my current account's address, I still get this error: There is already an account with the login name email@example.com.
This was probably timeout related. The user hasn't been active recently, if they still had this problem the bug can be re-opened.
