Although bug 34508 was fixed and many actions have been hardcoded to be fixed, there is still an issue with log actions registered by extensions.
However it's a different bug than bug 34508. The problem is not the format of the message. Wether the i18n message key is the same or not is not in the question here.
The problem is that the logging system is replacing variables with an HTML link instead of a bracketed wiki link for the target title.
Reporting in core instead of CentralAuth since this should be fixed centrally, not by hardcoding an exception for centralauth.
