Created attachment 731495 [details] workaround for chdir problems in older paramiko versions obnam-1.3-1.el6 does not work over sftp at all with the python-paramiko version delivered by EPEL. A workaround is included in obnam 1.4, I've also attached the specific changeset as a patch here (see also http://vlists.pepperfish.net/pipermail/obnam-flarn.net/2013-April/000709.html) and I can confirm that it makes the sftp plugin work.
Thanks for the report -- Obnam 1.4 landed while a bugfix update to Obnam for el6 was in the process of being pushed out, and the Obnam 1.4 update slipped through. Will push it now
