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

Qt Code: 
  1. QNetworkRequest request;
  2. request.setUrl(QUrl("http://www.discogs.com/search?type=releases&q="
  3.                             +QString(QUrl::toPercentEncoding(query))
  4.                             +"&f=xml&api_key="
  5.                             +Settings::instance()->discogsKey));
  6. request.setRawHeader("Accept-Encoding", "gzip");
  7. request.setAttribute(QNetworkRequest::User,"discogs search");
  8. ...
  9. QNetworkReply *reply = networkManager->get(request);
  10. connect(reply, SIGNAL(finished()), this, SLOT(handleNetworkReply()));
  11. connect(reply, SIGNAL(error(QNetworkReply::NetworkError)),
  12.             this, SLOT(handleNetworkError()));
  13. connect(reply,SIGNAL(metaDataChanged()),SLOT(handleNetworkState()));

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

Qt Code: 
  1. void TagsFiller::handleNetworkReply()
  2. {
  3.     QNetworkReply *reply = qobject_cast<QNetworkReply *>(sender());
  4.     if (!reply) return;
  5.     QString networkType=reply->request().attribute(QNetworkRequest::User).toString();
  6.  
  7.     int n = reply->request().attribute(QNetworkRequest::Attribute(QNetworkRequest::User+1)).toInt();
  8.  
  9.     QByteArray rawResponse = reply->readAll();
  10.     QByteArray response = rawResponse;
  11.  
  12.     if (reply->hasRawHeader("Content-Encoding") && reply->rawHeader("Content-Encoding")=="gzip") {
  13.         //we have to unzip the response, so we are trying to get content size
  15.         if (file.open()) {
  16.             file.write(rawResponse);
  17.             file.close();
  18.             response = deflateFile(file.fileName());
  19.         }
  20.     }
  21.  
  22.     //un-xml response
  23.     if (networkType=="discogs search")
  24.         parseDiscogsSearch(response);
  25.     if (networkType=="discogs release")
  26.         parseDiscogsRelease(response,n);
  27.     if (networkType=="discogs image")
  28.         parseDiscogsImage(rawResponse,"",n);
  29.     if (networkType=="freedb search")
  30.         parseFreedbSearch(response);
  31.     if (networkType=="freedb query")
  32.         parseFreedbQuery(response);
  33.     if (networkType=="freedb read")
  34.         parseFreedbRead(response,n);
  35.     reply->deleteLater();
  36. }

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:

Qt Code: 
  1. TagsFiller::~TagsFiller()
  2. {
  3.     if (!repliesStack.isEmpty()) {
  4.         foreach(QNetworkReply *reply,repliesStack.values()) {
  5.             reply->abort();
  6.             reply->deleteLater();
  7.         }
  8.         repliesStack.clear();
  9.     }
  10. }

Can anyone help me?
