Hi, when loading a page with a 304 code from cache, MiniBrowser crashes.
This happens because in that case, receiveData happens before receiveResponse.
Then, in that case, setCertificateToMainResource is called before a response has been set to the webresource. So, webkitURIResponseSetCertificateInfo(webkit_web_resource_get_response(priv->mainResource.get()), results in a null parameter being used in webkitURIResponseSetCertificateInfo).

Here is the crash backtrace:
