I don't get this error in my version, but it's not the latest. Actually, 
I'm reluctant to do a cvs update just now, for fear it might break my flows.

There is:

log.debug('Nifty debug message');

catch(e) { log.error(e); }

Messages are logged to flow.log and also to error.log, if appropriate. 
The problem is that logging an exception does not print a stack trace, 
which would be invaluable for debugging.
