I have forgotten my old password on http://de.wikipedia.beta.wmflabs.org/ so I got a one-time-password per email:
I got this error:
[067178d6] /wiki/Spezial:Passwort_%C3%A4ndern MWException from line 3782 of /srv/mediawiki/php-master/includes/user/User.php: CAS update failed on user_touched for user ID '228' (read from slave); the version of the user to be saved is older than the current version.
