The problem seems to have something to do with the python version, which is 2.5 on feisty, and 2.4 on edgy.
It works with python 2.4: if I copy the duplicity python modules into the python 2.4 tree and call duplicity with 'python2.4 /usr/bin/duplicity', everything works fine (despite a librsync version warning).
Using python2.4 to build and install duplicity from source also produces a working installation.
