Some scripts doesn't works with cjs, continuous "waiting for script"

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Goto http://jsfiddle.net/gEFsD/
2. Open firebug console
3. See the alert + the debug in the console

This is a webpage is controljs + a twitter timeline + a delicious timeline

The delicious timeline is ok, the twitter timeline fails.

There must be a link with the fact that the twitter timeline ask for 
downloading to desktop when opening the url in firefox. Delicious just display 
the javascript content.

This is the only difference I can see, this must affects a lot of <scripts>. 
Thanks for reading.
