New submission from ekorn <jonovik at gmail.com>:

It seems shlex fails on processing strings ending in space, causing this bug that I reported for IPython:
https://github.com/ipython/ipython/issues/1109

Fernando Perez made a minimal example of the problem, quoted below. As he points out, it would be best to fix this at the source, namely the shlex module.

Python 2.7.2 |EPD 7.1-1 (32-bit)| (default, Jul  3 2011, 15:13:59) [MSC v.1500 32 bit (Intel)] on win32
>>> import shlex
>>> lex = shlex.shlex(' ("a ")', posix=False)
>>> lex.whitespace_split = True
>>> list(lex)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\shlex.py", line 269, in next
    token = self.get_token()
  File "C:\Python27\lib\shlex.py", line 96, in get_token
    raw = self.read_token()
  File "C:\Python27\lib\shlex.py", line 172, in read_token
    raise ValueError, "No closing quotation"
ValueError: No closing quotation
