.gnupg directory chmod 777 (so the Key Admin page displays correctly)

This directory contains :

trustdb.gpg ** chmod 666 
secring.gpg ** chmod 604 
random_seed ** chmod 604 
pubring.gpg ** chmod 644 

.gnupg/errors  chmod 777 (especially if you run Cron or the ecryption fails)

** these files are automatically created once you upload a key
