I've seen the same error in Firefox 3.x on Mac OS X - it occurs when any
control is using UICallBack, and it's only on the response from
UICallBackServiceHandler.
Having a snoop at the HTTP traffic, there's no Content-Type set on the
response from UICallBackServiceHandler, which could be the cause of the
error message.
There's also no Content-Length either, as there is in the standard event
loop responses, so it looks like it's using a different code path to serve
the JS.
A fix is probably as simple as adding in a Content-Type header (the lack of
Content-Length isn't a big issue, as Tomcat etc. will just chunk encode the
response).
cheers

Tim,
thanks for the hint. A quick glance at the code seems to affirm your
assumption about the different code paths. You could file a bugzilla
to keep track of it.
Cheers,
Rüdiger
