I have delays of 3 to 6 seconds using non-native dialogs. A native dialog is able to access the same folders instantly.

Qt is caching file dialog data in ~/Library/Preferences/com.trolltech.plist. Try deleting this file; perhaps it contains corrupted data.

Also try the following program. I have identical browsing times with this code and QGIS. If this example is also slow, you should submit a bug to Trolltech.

#include <QApplication>
#include <QFileDialog>
int main(int argc, char *argv[])
  QApplication app(argc, argv);
  QFileDialog dialog;
  return dialog.exec();
