near as I can tell, this function is _only_ called from subprocess_spawn
like this:

def subprocess_spawn(sh, escape, cmd, args, env):
    return exec_subprocess([sh, '-c', ' '.join(args)], env)


which is in turn set up by default this way:

SHELL: 'sh'
SPAWN: <function subprocess_spawn at 0x7f7fe858c158>


Is there any chance you've reset SHELL in your environment? To something
that is not found on your Ubuntu system? An example would indeed be good.
