Details:

Duplicity crashes on files inside directories without executable bit set
(chmod -x). It should at least print proper error message, and f.e. skip such
files on --force.

Steps to reproduce:
% mkdir testdir
% echo foo >testdir/testfile
% chmod -x testdir
% duplicity --no-encryption testdir file://backup

Results:
Traceback (most recent call last):
