Obnam is supposed to report the right version number in the log file or with "obnam --version", and if it isn't 1.0 then something's wrong. - -Do you have the right version of the Larch Python library installed? That stack trace looks like there's an old version installed. Are you running on Debian? Ubuntu? Somewhere else?
