Page hits that don't have PATHINFO stuff on them but use bare script + query string such as:
http://lazarus.local/trunk/index.php?title=Special:Foobar
spew a warning like this:
<b>Warning</b>: Invalid argument supplied for foreach() in <b>/Library/WebServer/Documents/trunk/includes/WebRequest.php</b> on line <b>128</b><br />
This error is due to something other than an array being returned from WebRequest::getPathInfo(), which has apparently been rewritten in r81363
