I too can confirm exactly the same issue - I am able to copy a file but not a directory from network mounted share. I get a "permission denied" error message. In addition I have exactly the same problem with ftp. Interestingly, as stated by Gerard and miraceti, browsing to the "~/.gvfs" folder allows me to copy folders no problem.
Additionally, issuing the command "smbclient //SERVER_NAME/SHARE_NAME -N -c 'recurse; mget DIRECTORY_NAME/'" gives no errors.
