Comment (by adfernandes):

 Hmm... looking at the log, all the dependencies seem to be at their latest
 (correct) version.

 I just removed and re-installed `ansible` and cannot reproduce,
 unfortunately.

 I'll try a couple more things, including updating to ansible 2.4.1 (due
 out in a few days) and see if that fixes things.

 Sorry for the problem - it's a real puzzler!
