Certificate check using XMLHttpRequest (from QML) on HTTP server (no HTTPS)

Hi all,

Just downloaded the fresh Qt 5.7, and compiled some projects.

One of them heavily uses web services requests. On the testing server, the communication is done using HTTP (no SSL is configured out there). However, since 5.7, the application isn't allowed to make a XMLHttpRequest.send() to that server. Instead, on trial, the following message is displayed several times in the console: "qt.network.ssl: Error receiving trust for a CA certificate".

I even tested the request itself on "http://www.google.com", with same results. It seems very reproductible. As this application is essentially working over HTTP, I presume this is a bug ?

This used to work (and is still working) with 5.6.
