obnam 0.23 crashes when started without --log option. Here is what it spits out on the console:

    user@host:~$ obnam backup ./
    CRITICAL:root:Traceback (most recent call last):
      File "/usr/lib/python2.6/dist-packages/cliapp/app.py", line 132, in _run

        handler = logging.NullHandler()
    AttributeError: 'module' object has no attribute 'NullHandler'

This is actually a bug in cliapp 0.22, which switched to using
`logging.NullHandler`. That only exists in Python 2.7, and you're
using 2.6. Workaround: `obnam --log=/dev/null`. I'll release a new
cliapp soon, it's already fixed in bzr. --liw
