Hi Germain,
I've confirmed that the basho bench drivers for riakclient and riakc_pb do
not provide a content-type when submitting key/value pairs to Riak. This
should not cause problems while running the benchmark.
Which driver were you using when you noticed the webmachine errors? Were you
making GET requests for keys created in the benchmark against the REST API
after the benchmark?
Thanks,
Dan
