<div id=lst></div>
then
$(‘#lst/div’).length gives error, but $(‘#lst’).find(‘div’).length gives 0

The same problem also occurs with "#lst > div". This seems to be because the method for evaluating the ">" and "/" tokens sends #lst's firstChild to jQuery.sibling(), which then tries to get its parentNode. Boom! Null element reference doesn't have a parentNode! It can probably be fixed by
A) making jQuery.sibling() check for a null value for its 'elem' argument or
B) changing jQuery.token[3] to something like "a.firstChild?jQuery.sibling(a.firstChild):[]".
