From the manual page:

--gpg-options options
    Allows you to pass options to gpg encryption. The options list should be of the form "opt1=parm1 opt2=parm2" where the string is quoted and the only spaces allowed are between options.

This suggests that options like --homedir=/foo can be passed with --gpg-options "homedir=foo". This is certainly not the case. Please include an example like --ssh-options

duplicity --gpg-options "--no-options --homedir=/home/user/.gnupg"
