lftp-3.7.8: debug issues (2)

1. When run "debug off" I still see some errors in the session:
mirror: Access failed: 550 filename.txt: Permission denied.
mirror: Access failed: 550 filename.txt: Permission denied.
mirror: Access failed: 550 filename.txt: Permission denied.

Is this intentional?

2. Can you please add the debug variable value in the set -a output, so 
one could see whats set to?

lftp :~> set -a | grep -i debug
lftp :~>

Justin.
