Pending network replies won't let program to quit

Hi, I have a problem. I'm using QNetworkAccessManager:

Code:

---

QNetworkRequest request;
request.setUrl(QUrl("http://www.discogs.com/search?type=releases&q="
                            +QString(QUrl::toPercentEncoding(query))
                            +"&f=xml&api_key="
                            +Settings::instance()->discogsKey));
request.setRawHeader("Accept-Encoding", "gzip");
request.setAttribute(QNetworkRequest::User,"discogs search");
...
QNetworkReply *reply = networkManager->get(request);
connect(reply, SIGNAL(finished()), this, SLOT(handleNetworkReply()));
connect(reply, SIGNAL(error(QNetworkReply::NetworkError)),
            this, SLOT(handleNetworkError()));
connect(reply,SIGNAL(metaDataChanged()),SLOT(handleNetworkState()));

---

and then working with the reply in the slot handleNetworkReply():

Code:

---

void TagsFiller::handleNetworkReply()
{
    QNetworkReply *reply = qobject_cast<QNetworkReply *>(sender());
    if (!reply) return;
    QString networkType=reply->request().attribute(QNetworkRequest::User).toString();
 
    int n = reply->request().attribute(QNetworkRequest::Attribute(QNetworkRequest::User+1)).toInt();
 
    QByteArray rawResponse = reply->readAll();
    QByteArray response = rawResponse;
 
    if (reply->hasRawHeader("Content-Encoding") && reply->rawHeader("Content-Encoding")=="gzip") {
        //we have to unzip the response, so we are trying to get content size
        QTemporaryFile file;
        if (file.open()) {
            file.write(rawResponse);
            file.close();
            response = deflateFile(file.fileName());
        }
    }
 
    //un-xml response
    if (networkType=="discogs search")
        parseDiscogsSearch(response);
    if (networkType=="discogs release")
        parseDiscogsRelease(response,n);
    if (networkType=="discogs image")
        parseDiscogsImage(rawResponse,"",n);
    if (networkType=="freedb search")
        parseFreedbSearch(response);
    if (networkType=="freedb query")
        parseFreedbQuery(response);
    if (networkType=="freedb read")
        parseFreedbRead(response,n);
    reply->deleteLater();
}

---

But if the connection with the Internet is down and I'm closing the dialog without timeout waiting, I have network replies still processing, and my program won't quit at all.
I tested it in Windows (Qt 4.6) and Linux (Qt 4.5), the problem is still present.
I know that QNetworkReply has slot abort(), but this solution doesn't work:

Code:

---

TagsFiller::~TagsFiller()
{
    if (!repliesStack.isEmpty()) {
        foreach(QNetworkReply *reply,repliesStack.values()) {
            reply->abort();
            reply->deleteLater();
        }
        repliesStack.clear();
    }
}

Can anyone help me?
