This is a way I get the bug.
1) I joined community with login Maestro on the Dolphin 7 beta7 demo on the demozzz.com
2) after some simple activity (avatar upload, some comments) i have edited my profile and set Relationship to: "It's complicated"
3) I have changed password.
After this I can't login anymore neither old password nor new. When I try to reset password with "forgot password" link, I see
SELECT `ID` FROM `Profiles` WHERE `ID` != 255 AND `RelationshipStatus` = 'It's Complicated'
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 's Complicated'' at line 1
