I remember this happening to me once while writing Attribute test cases.
The problem which wasn't at all obvious to me was that the constructor that
uses the URI couldn't  be passed an empty string.  You are not suppose to
use that constructor if you don't actually have a URI

OK
Attribute attr = new Attribute("test", "prefx", "http://some.other.place",
"value");

Not OK
Attribute attr = new Attribute("test", "prefx", "", "value");

This would be a problem of course of if you didn't know for certain at
design time whether or not you actually had the URI.

Are you passing an empty string to the URI argument?
