How to properly stop QNetworkRequest ?

[#Dragon]

Hi, I've got a problem with my HttpClient, when I'm trying to stop/cancel request my application crashes... How can I cancel it properly ?

After when I'm trying to stop by this function:

void HttpClient::stop(){
    if(m_reply) {
       m_reply->abort();
    }
}

void HttpClient::stop(){
    if(m_reply) {
       m_reply->abort();
    }
}

it crashes on: loop.exec();

in function 'wait for finish'...

void HttpClient::waitForFinish(QNetworkReply *reply)
{
    QEventLoop loop;
    connect(reply, SIGNAL(finished()), &loop, SLOT(quit()));
    loop.exec();
}

void HttpClient::waitForFinish(QNetworkReply *reply)
{
    QEventLoop loop;
    connect(reply, SIGNAL(finished()), &loop, SLOT(quit()));
    loop.exec();
}

To copy to clipboard, switch view to plain text mode 

QString HttpClient::get(const QString &url)
{
    if(url.isEmpty()){
        Logger::getInstance()->Error(trUtf8("HttpClient: GET Response <Url is empty!>"));
    }
    m_reply = m_manager->get(*this->generateRequest(url, false));
    waitForFinish(m_reply);
    if(!m_reply){
        return "";
    }
 
... code

QString HttpClient::get(const QString &url)
{
    if(url.isEmpty()){
        Logger::getInstance()->Error(trUtf8("HttpClient: GET Response <Url is empty!>"));
    }
    m_reply = m_manager->get(*this->generateRequest(url, false));
    waitForFinish(m_reply);
    if(!m_reply){
        return "";
    }

... code

This problem occurs sometimes, not always. I think that if, in another thread still performs and here is aborted it causes this crash...
Any idea ?

Thanks for any help
