No I think this can be considered an attact since someone could make a link in a webpage or a autoredirect to something like
code:
<a href="file://path/to/path/to/path/to/path/to///////path/to//////">Free WLM Invites</a>
Something like that and the person would click it just to have the browser crash. I dont see how this could be a DoS attact but surely a anyoying prank
