After updating ZF2 application to latest master (9f4dd7f13c) all controllers return an empty JSON response:
{"content":[]}
Tracing JsonRenderer::selectRenderer, $match at Line 106 succeeds because the browser (Google Chrome 18) sends */* in the Accept header, which triggers the JsonRenderer despite the fact that text/html is the primary Accept type and the controller returns a ViewModel.
