If you attempt to move a page to a title that you don't have permission to create (ex: attempting to move a page into MediaWiki namespace as a non-admin, moving a JS or CSS page into someone else's userspace as a non-iadmin), the resulting error message will show up twice.

This is because protection is checked separately against the target. In the former scenario, the double error messages are for edit and move rights against the target page.
