Started happening recently - actually right after I enabled uca-default collation. Here's one full backtrace: [10-Feb-2011 04:08:14] PHP Warning: DOMDocument::loadXML() [<a href='domdocument.loadxml'>domdocument.loadxml</a>]: Empty string supplied as input in

I've traced it to this call in Message.php: $message = str_replace( $message, $replacementKeys ); in ::replaceParameters
Fixed in r81878.
