    Description

      ...When invoked in a slot.

      Every time getOpenFileName dialog is opened in a folder that contains many folders/files, the application hangs for about 10 seconds.

      Reproducible by

      #include <QApplication>
#include <QTimer>
#include <QFileDialog>

class Open : public QObject
{
    Q_OBJECT

public:
    Open() { QTimer::singleShot(0, this, SLOT(open())); }

public slots:
    void open() { QFileDialog::getOpenFileName(0, "Hangs", qgetenv("WINDIR")); }
};

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QFileDialog::getOpenFileName(0, "Works", qgetenv("WINDIR"));
    Open obj;
    return app.exec();
}

#include "main.moc"

      Doesn't happen with Qt4
