We traced it down to this Webmachine change:
https://github.com/basho/webmachine/commit/d7dbbddeb9e6a9a415f7a7f09261dfcd3c2bd001

RabbitMQ management plugin bundles its own version of Webmachine. Can it be that you
somehow have another copy on the global Erlang load path? (wrq.beam)

There were reports of similar issues earlier and uninstalling a system-wide package
that was included into Erlang code path helped, e.g.
