Try using addCallbacks instead of addBoth. Then, you can logically separate
code to handle/print errors from "normal" code.
This will simply print no error in the log:

That's because you discarded the twisted.python.failure.Failure object by
using _stop for your errback and not doing anything with the arg. Similar
to try/except with a "pass" in the "except" clause.
def log_error(failure):
log.err(failure.printTraceback())

Use d.addCallbacks(_stop, log_error) instead of addBoth/addErrback. Also,
you probably want "log.err(failure.getTraceback())" instead of
"log.err(failure.printTraceback())". printTraceback does not return a
meaningful value IIUC.
I don't get any traceback either.

Your traceback went to stdout whereas you were probably watching stderr or a
log file.
