Hello Kenneth,

I did take a look at issue901 and you have it very well summarized in a
comment from 2 days ago:

" The only way I have been able to reproduce this is by setting up like
this:

   - full
   - clear local cache, ~/.cache/duplicity (very much not advised)
   - inc, collection-status, or other action that requires looking at the
   manifest."


I will keep an eye on that issue.

Thanks,
