I've been able to reproduce this bug using Firefox 3.6.3 (ubuntu 10.4) with the filename of ".&".  Here's howto reproduce very quickly:

    touch .\&
    firefox $(pwd)

http://www.aspca.org/
crashes with a similar message:

XML Parsing Error: not well-formed
Location: http://www.aspca.org/
Line Number 21, Column 116:<iframe src="http://img-cdn.mediaplex.com/0/15312/universal.html?page_name=aspca_homepage_master_tag&ASPCA_Homepage=1&mpuid=" HEIGHT=1 WIDTH=1 FRAMEBORDER=0></iframe>

In contrast Safari displays the page.  Surprisingly, firefox displays it ok too!

URL-escaping won't escape random HTML crud.

In any case, this is fixed in gecko 2.0.
