 The inability to have spaces within arguments is a defect, and a rather
 fundamental one.

 If the GUI doesn't need to understand the command(s), the string should be
 passed verbatim to Popen(..., shell=True). But this will allow arbitrary
 shell commands, including redirection, pipelines, for/if/while, etc.

 If you need to parse a string into program and argv[], consider using
 shlex.split():
