For debugging...
There is a
Notice: Undefined property: DOMDocument::$documentElement in
/home/~/public_html/w/includes/parser/Preprocessor_DOM.php on line 179 with all
error reporting turned on.
Not a warning or fatal.
I added
if ( !$obj ) {
throw new MWException( "No result for XML: $xml" );
}
Right before line 179, which is where return $obj; is
Still same message

Huh, that's interesting. Going through the backtrace, it looks like
Preprocessor_DOM::preprocessToObj is returning null when it really should never
do that.
For debugging, can you add the following at the end of the file
/includes/parser/Preprocessor_DOM.php (just before 'return $obj;'):
if ( !$obj ) {
throw new MWException( "No result for XML: $xml" );
}
And report the new error message and backtrace you should get?
