Hermod,
This sounds like a bug in HttpClient. Would it be a big deal for you to
reproduce the problem with a test case?

HttpClient handles transfer encoding completely transparently. There is
nothing that needs to be on the consumer side. Just read data from the
content stream of the response entity.

OK. I can reproduce the problem and confirm it is a bug. I'll fix it
when I am back from vacation in 10 days.
