[webkit-dev] strange problem when inserting nodes to DOM tree

Hello. I have strange problems when HTMLParser tries to insert new nodes. And as a result, the HTML page isn't rendered correctly. The ContainerNode::addChild() returns NULL on "#text" and "HTML" nodes. The second problem is in HTMLParser::parseToken(). There's a token that gets into the parseToken() method which contains basically the whole HTML page without the HTML tag elements. So it looks parsed and includes javascript code that is a part of the HTML page. Any ideas on what's going on or what could cause this action? Greets, Luka
