dropbox

With duplicity 0.8.01 and python3-dropbox 9.4.0, I get the following:

Exception [Can't mix strings and bytes in path components]:
| Traceback (most recent call last):

| raise TypeError("Can't mix strings and bytes in path components") from None
| TypeError: Can't mix strings and bytes in path components
dpbx code error "Can't mix strings and bytes in path components"

Other backends work.

I'm on Fedora 30, but I've only put 0.8.01 in rawhide (I'm the Fedora duplicity rpm maintainer).
