duplicity: error: no such option: -z

[smet-dk]

I created a cronjob exactly as described in the readme.

  # GPG options (compression and algorithms)
  cipher_algo    'aes256'
  digest_algo    'sha512'
  compress_algo  'bzip2'
  compress_level 6

The compress_level becomes -z6, and then calling the script (cronjob) and then duplicity breaks with the errorcode in subject. I think this might be an issue with escaping, but I can't seems to find out how to fix it. I just realized that the '-z' (and more) was committed just 7 days ago. Maybe it's quotation, maybe it's that '-z' doesn't get parsed right... Please tell me if you need more info...

Hi again.

A possible fix could be the patch that I quote below (don't know how else to do it, sry). In my sitation, it seems to be bad quoting, that sends the GPGOPT directly to duplicity, instead of through to gpg...

patch -p1 < GPGOPT-z.patch

I had some issues with quoting the gpg arguments before, though my approach fixed it. Thanks for reporting, I'll check this next week and hopefully merge it (maybe alongside with moving GPG_OPTIONS alongside DUPLICITY_ARGUMENTS.

I'm having the exact opposite problem. When using your patch, I get the error you're describing, when not using it it works :) - Investigating.

[chr4]

Ok, both seem to work. Mmh, I'll accept this if it works for more people :)

Released in v1.2.2. Thanks again!
