Bug#929324:

I've just done some debugging, issue seems to be with debian curl, and not just the php extension for it. I'll open a new ticket under curl and this issue can be closed.

Bug#929324: Fwd: php-curl inability to send blank accept headers

Package: php-curl Version: 1:7.0+49 Hello there! I noticed using guzzle that we are unable to send a blank accept header, so I had tested the same thing using the PHP-Curl extension. The behavior seems to be the same; a '*/*, ' value is being sent using the underlying 'Accept;' CURLOPT
