Re: [openstack-dev] swiftclient report that header value 120 must be of type str or bytes, not , the detail info is like the following

[Tim Burke]

This is the result of a fairly recent change in requests [1], released 8 Aug. 
While the enforcement of header-value types is fairly recent, they've 
documented since 2.0.1 that headers must be byte- or unicode-strings [2], and 
more recently clarified it in their quick start guide [3]. It looks like this 
has been addressed in smaug already [4], but I'd expect that you could 
downgrade requests to 2.10.0 while waiting for a new release of smaug.
