This is quite odd. I've been using the current version of duplicity to
produce incremental backups since last week. Today is monday so we start
a fresh backup, which fails. It seems that invoking duplicity to create
any kind of full backup also fails with the following output:
$ duplicity --full /home/sam/bin file:///tmp/foob
Traceback (most recent call last):

I'm not sure why the stack trace is different on the two machines. The
desktop is running testing with a few packages pulled from unstable, the
server is running etch with duplicity backported from unstable. Both
systems have the same version of gnupg, python-gnupginterface and
python-pexpect.
Severity serious because I can't run duplicity at all now, on two
different machines.
