Running any pootle commands in shell produces an error similar to the one below.

$ python manage.py sync_stores
2014-03-06 08:39:29,305 INFO Change ID is zero, ignoring altogether.
2014-03-06 08:39:30,196 ERROR Failed to run sync_stores over /ro/activist_orientation_guide/'s files

2014-03-06 08:39:40,040 ERROR Failed to run sync_stores over /zh_TW/venus_project_site/'s files

Trying python26 in place of python yields a different error

$ python26 manage.py sync_stores
