The cause of the crash is an assertion failure that we do not emit 
an error message (grant not found) and then return "ok".  The 
assertion is valid, and we were ignoring the buggy behavior prior 
to the "Diagnostics" result-verification.

Use an error handler to mutate innocuous missing-grant errors, when 
removing routines, into warnings.
