Fabric is giving me an EOFError when I try to chown a directory. It only happens if I run a subprocess from a python script that fabric runs immediately before.

From my fabfile:

...
with settings(warn_only=True):
    run('python my_scripts/import_local.py')
sudo('chown www-data:www-data /opt/mm/my_project/uploads -R')

If I comment the lines below out of my_scripts/import_local.py I get no error:

    p = subprocess.Popen(command.split(), stdout=subprocess.PIPE,
                         stderr=subprocess.PIPE)
    result = p.communicate()[0].splitlines()
    if result:
        print result

With the subprocess lines left in I get this traceback (running with --show=debug):

[xx.xx.xxx.xxx] sudo: sudo -S -p 'sudo password:'  /bin/bash -l -c "cd /opt/mm/my_project/current && source environment.sh && chown www-data:www-data /opt/mm/my_project/uploads -R"

What happens when you run:

$ ssh xx.xx.xxx.xxx -t'sudo -S -p "sudo password:"  /bin/bash -l -c "cd /opt/mm/my_project/current && source environment.sh && chown www-data:www-data /opt/mm/my_project/uploads -R"'
