by a cvs merge, a form declaration dropped out.
No complaint while parsing the the config even though a <action ... name=""
later referenced the missing form.
Only, once the form is executed, it is found missing.
It would save programmers a lot of time if such errors would be raised at load
and not only at the end of lenghty, often manual test runs.
