Description:
Several users have reported receiving internal errors when attempting to load page histories, diffs or the edit window. The message displayed is:

Detected bug in an extension! Hook CentralAuthHooks::onGetUserPermissionsErrorsExpensive failed to return a value; should return true to continue hook processing or false to abort.

Backtrace:

and appears to be connected to CentralAuth: the common factor between the two users reporting the error is that a global account exists for the username, but the local account is not part of that global account.
