This looks like a problem with `at' assuming that everything in the
environment is a valid shell assignment statement (or equivalent).  Since
the environment can include arbitrary strings, that's not a safe
assumption.  Bash, for instance, ignores and passes environment strings
that it doesn't recognize as valid assignment statements.

I'd send it to your vendor.  If appropriate they can send it upstream.
