Random-seeming "Uncaught exception escaped" with no reference to my code

[Richard]

Every so often, while running in Dev Mode, I'll get this exception (or something like it). Is this some under the hood local-only issue I don't need to worry about, or does it hint as something I should fix?  Is there anything I can do about it?

Chrome has been known to randomly throw those exceptions. That is
assuming you are running chrome. See:
http://code.google.com/p/google-web-toolkit/issues/detail?id=5778#c65,
it might be related to the issue you are experiencing.

Best regards,

Alfredo

That's probably it, thanks Alfredo.
