Description:
I used a simple text style template in MediaWiki:Categorytree-header. The text
does show on that page, but on CategoryTree it shows up as {{{1}}}.
Version: unspecified

Note that the general case here is us being nice and putting in a wikitext
header, but then doing something like:
$wgOut->addWikiText( wfMsg( 'someheadermessage' ) );
wfMsg() will allow the message cache to do message transformations, which messes
up templates and so forth, those get replaced at that time. This can usually be
addressed by changing this to:
$wgOut->addWikiText( wfMsgNoTrans( 'someheadermessage' ) );
This fixes the behaviour, and as a nice side-effect, should shave a tiny bit of
time off the whole operation, since a relatively expensive transformation step
isn't applied twice (once in wfMsg(), once in the implied parser run).
