Unexpected error: (NS_ERROR_DOM_NOT_SUPPORTED_ERR): Operation is not supported

What steps will reproduce the problem?
1. data.rebioma.net
2. no interaction with the site is necessary
3. mouse over landing page? possibly not even necessary

What is the expected output? What do you see instead?
Error popup, coming with frequency (see below). Rebooting tomcat, mysql,
the entire server, do not seem to clear this up...

This page:
http://code.google.com/p/gwt-maven2-starter-app/issues/detail?id=8#c4
which reports on a similar error, indicates that perhaps an update
 to 1.7 GWT jars can help, but I have not tried this
