[S3tools-bugs] --cf-invalidate option causes crash

[Casey S. <cas...@ba...>]

If the "—cf-invalidate" command line option is used, and there are files to upload, s3cmd will crash with a “
TypeError: 'module' object is not callable” error. This does not happen if the flag is removed, or if there are no files to sync.

This is on FreeBSD 11.0, with Python 2.7 and s3cmd 1.6.1.
