If a page has been moved since it has been protected, the one-entry log extract that appears under [[MediaWiki:Semiprotectedpagewarning]] records the new "moved protection settings from Foo to Bar" instead of the actual protection act. Not sure how best to resolve this, but it's definitely a bug.
Volunteered by Brian during bug triage.
Possibly looking into filtering based on log_action (we have an index on it now and all I think ;)
