Solution

This repo https://github.com/alexreg/git-bzr-ng/commits/master has a wrong solution

-  proc = subprocess.Popen(cmd, stdout=stdout, stdin=stdin)
+  proc = subprocess.Popen(cmd, stdout=stdout, stdin=stdin, shell=True)

because in Linux "shell=True" don't run args[1] etc.

cat /etc/issue
Ubuntu 13.04 \n \l

# arg is a program that print its arguments
python -c "import subprocess; subprocess.Popen(['arg', 'a'])"
0: arg
1: a

python -c "import subprocess; subprocess.Popen(['arg', 'a'], shell=True)"
0: arg

The right solution is therefore

if hasattr(cmd, '__iter__')
    proc = subprocess.Popen(cmd, stdout=stdout, stdin=stdin)
# a bug http://stackoverflow.com/a/36327/1299708 require shell=True
else
    proc = subprocess.Popen(cmd, stdout=stdout, stdin=stdin, shell=True)
