in case we use ob_start() on multiple times, we have more output buffers (more levels of them), and we sometimes dont know of how many to dispose (in case of errors)

p.s. i think ob_end_clean() doesnt really "clean" the data collected on 4.2, and i think i spotted this somewhere else..

function condor_error($errno, $errstr, $errfile, $errline)
{
        $errors = array(E_USER_ERROR, E_ERROR, E_PARSE);
        if (in_array($errno,$errors)) {
                //      ob_end_clean();
                //      ob_end_clean();
                //      ob_end_clean();
                echo "<B>FATAL</B> [".$errno."] ".$errstr."<br>\n";
                echo "Fatal error at line ".$errline." of file ".$errfile;
                echo ", PHP ".PHP_VERSION." (".PHP_OS.")<br>\n";
                echo "Aborting...<br><br>\n\n";
                exit;
        }
}

set_error_handler("condor_error");


replace the //ob_end_clean() with ob_end_clean_all();

if its bogus, then i apologise for wasting your time :)
