Create_Group fails with permission argument about google-apps-shell HOT 4 OPEN

Same issue here using gas in CLI under Ubuntu 11.04 (Python 2.7.1)

Traceback (most recent call last):
  File "/home/feag/Google/gasi/gas.py", line 935, in <module>
    __main__()
  File "/home/feag/Google/gasi/gas.py", line 932, in __main__
    execute(args[1:])
  File "/home/feag/Google/gasi/gas.py", line 923, in execute
    whitelist_functions[call_function](credential, **dictionary)
  File "/home/feag/Google/gasi/gas.py", line 685, in create_group
    assert permission.length>0, 'Invalid permission argument.'
AttributeError: 'str' object has no attribute 'length'

Any followup? This is would be very useful if it worked.

I am also running OSX 10.7.3, 1.7GHx Core i5, 4GB RAM, 128GB SSD

Exception in Tkinter callback

Same here: OSX Mavericks 10.9.1 on MacMini Server Late 2012.
running python with sudo has no effect.
