Also reproducible on any wiki through Vector's SimpleSearch bar.
I can confirm on mediawiki.org but can't reproduce this locally, either with OpenSearchXml installed or not... on a local test wiki I get multiple results when searching for 'mediawiki:'.
Looks like bug 26443 or at least related to that
