GNOME Bugzilla – Bug 162089
Entity & in tag attributes raise error in XML normalization

Have a <a href="example.com/?bla=1&bla=2">test</a> inside a correctly written markup. The error arise only when & is there. If "&" is there you have no problem. There is also no problem with other entities (I tested with è).
I think I've fixed this in CVS HEAD now.
