set_acl

[numericlee]

Using boto 2.48 and python3.6 in a conda linux environment

k.set_contents_from_filename(image.png)

successfully creates a file

but
k.set_acl('public_read')
gives me an assertion error ( assert acl-Str in CannedACLStrings)`

I have to do it manually
this may be related to #3707

@numericlee , could you tell me what you did as a manual work-around?
