Steps to Reproduce:
# semanage module -d
Traceback (most recent call last):
  File "/usr/sbin/semanage", line 937, in <module>
    do_parser()
  File "/usr/sbin/semanage", line 916, in do_parser
    args.func(args)
  File "/usr/sbin/semanage", line 572, in handleModule
    OBJECT.set_enabled(args.module_name, False)
  File "/usr/lib/python2.7/site-packages/seobject/__init__.py", line 397, in set_enabled
    for m in module.split():
AttributeError: 'NoneType' object has no attribute 'split'
# semanage module -e
