reset password doesn't work

I created my account using OpenID. When I tried to change my generated password I got error "old password is wrong". Then I used reset password feature twice and each time when I tried to change the generated password I got the same error...

I'll change your password and send you a new one in a private notification.

You will need to update your new password after this, for it to take effect.

..Trying again without being logged in as mirror. :-)

That worked but it seems there is a serious error in this feature... Thanks
