KeyError: 'query'

Failure is highly repeatable and happens for queries of the form

	select * from table

The REQUEST shows:

form
SUBMIT 'Submit Query'
cookies
tree-s 'eJzTyCkw5NLIKTDiClZ3hANXW3WuAmOuxEQ9AIOOB9Q'
__ac_name 'allison'
lazy items

other
n_ 5

REQUEST_METHOD'GET'
HTTP_KEEP_ALIVE'300'
SERVER_PROTOCOL'HTTP/1.1'
QUERY_STRING'SUBMIT=Submit+Query'

Somewhere between manage_testForm and manage_test something fails,
possibly as the query goes off to be rendered through the DocumentTemplate
mechanism.  Right at the moment, I'm stuck.  Advice, clues appreciated.
