WebKit appears to drop the last 512 bytes from a QNetworkReply (custom protocol) implementation.

I implement a custom protocol (using the same method I used successfully in a Qt4.7.x release previously) using QNetworkReply, QNetworkAccessManager and a subclassed QWebView. It returns e.g. some file from a resource. However, in Qt4.8.3 WebKit appears skip the last 512 bytes of this QNetworkReply. If I pad the reply with 512 bytes of 0, then HTML and image content render properly. *This may be related to QTBUG-24110.
