Ah, indeed I get the error if I use your document class, so this bug actually seems to be in the IEEEtran.cls file ('ENGLISH' does not look like a proper language, that should be 'english').
This works fine with the default documentclasses (article, scrartcl, book, etc.), so I'm very much inclined to reject this bug unless someone can convince me that this is a bug in the tetex package.
