Like any cron, the environment is severely restricted to avoid using any
but core utilities.  I suspect this is the problem.  From the traceback,
duplicity was unable to execute gpg.  You probably need to add that path
to the launchd path.  I'm not sure how to do that on a Mac, but it may
be as simple as adding "export PATH=$PATH:/path/to/dir/with/gpg" to the
script you run.

The fact that it runs correctly outside the launchd environment (from
your next message) tells me that's probably the correct answer.

This is a new feature that checks for proper resources before starting.
 The two I check are Max Open Files and temp space.  Yours was the right
solution to the problem.
