AttributeError: 'list' object has no attribute 'startswith' when using verify

[iceflatline]

I am encountering the following error when running the following verify command on FreeBSD 9.1-RELEASE:

/usr/local/bin/duplicity verify --include /mnt/files/backup/ --exclude '**' scp://backup@192.168.20.6//mnt/files/weekly/ /mnt/files/

[Tom Callahan (anomaly)]

I was able to get this working by inserting the following between lines 158 and 159 of _ssh_paramiko.py

            if isinstance(self.config['identityfile'], list):
                self.config['identityfile'] = self.config['identityfile'][0]

I was not able to correct the problem by inserting Tom's code between lines 158 and 159 of /usr/local/lib/python2.7/site-packages/duplicity/backends/_ssh_paramiko.py . However I was able to correct the problem by *replacing* lines 157-159 with this code.

A workaround is to specify the Identity file on the command line:

  duplicity .... --ssh-options="-oIdentityFile=<file>" ....
