Underlying Symbian network interface is not closed after QNetworkRequest has finished. This is easy to notice because 3G connection icon stays active after the request. This is especially problematic on apps accessing network rarely. It leaves impression to end user that connection is active all the time.

Probably connection shouldn't be closed immediately after the request because new request might follow quickly. But it seems that now the connection is never closed. Even after deleting both QNetworkRequest and QNetworkAccessManager objects connection seems to stay open.

Problem is easy to reproduce with a following snippet:

manager = new QNetworkAccessManager(this);
request = new QNetworkRequest(QUrl("http://www.google.com"));
connect(manager, SIGNAL(finished(QNetworkReply*)),
        this, SLOT(replyFinished(QNetworkReply*)));
manager->get(*request);

void replyFinished(QNetworkReply* reply)
{
reply->deleteLater();
}
