I have temporarily disabled the experimental WikiMaps extension that I worked on at the Zurich hackathon. It used a new content type, GeoJSON. Now if I try to index my wiki, I get an uncaught exception and the script dies. Instead, it should just skip the page and could report a warning about the issue.

In core, the code in the Revision class that handles getting the content first tries to get the ContentHandler, via ContentHandler::getForModelID. This throws plain MWException instead of MWContentSerializationException.

MWException from line 324 of /Library/WebServer/Documents/php-master/includes/content/ContentHandler.php: No handler for model 'GeoJSON' registered in $wgContentHandlers
