The problem is the code tries to put the whole article into the feed,
which chokes a lot of browsers and feed servers. Someone on this list
devised their own RSS page with just what they wanted. I hacked the
code in includes/QueryPage.php/feedItemDesc(), to be this:
if( isset( $row->text ) ) {
$text = "<p>" . htmlspecialchars( wfMsg( "summary" ) ) .
": " .
$text . "</p>\n";
}
In other words, I cut off the row->text part of the string. That seems
to have helped a lot. You may want to search the archives for the more
elegant solution.
