Since bug 15936 and despite followups, "Mark this page as patrolled" is offered even for own creations/revisions, which results into "You are not allowed to patrol pages that you have created."
Confirmed with 1.22wmf9 (f0f11ee) on en.wiki.
Version: 1.22.0
Severity: normal
Marius, I assume this is something from your recent changes? (Only assuming, didn't look at changelog :) ).
