What e-mail did you receive initially? Can you paste the contents here (not your login credentials of course)?

The password reset form lets you enter a username or e-mail address to begin a password reset. There's nothing stopping another user from entering your username, which will then send an e-mail to you. It's completely harmless because that won't reveal anything to a third party, but somebody could be probing for security holes.

Edit: Was it this e-mail?
