    Description

      When using a QNetworkAccessManager instance across q_event_loop.exec() the errors emitted from the QHttpNetworkReply object are not getting received from the QNetworkAccessHttpBackend object.

      I debugged it as best as I could. As far as I can tell the QHttpNetworkReply object is not connected via the signal finishedWithError to QNetworkAccessHttpBackend.

      I've attached a simple example of the issue which reliable reproduces the error. This issue might be related to how I'm provoking the network error, I'm subclassing an IODevice which returns -1 when it's read from. I discovered this issue when I was unit testing for the condition of a http file post, when the source file drive goes offline.

      Additional odd behavior.
      1. If the first net request returns an error on the first call to q_event_loop.(), then the second time when the net request returns an error then q_event_loop.exec() will return correctly. However if the first request returns successfully then the second time it won't return correctly.
