OSX下的QFileDialog会向控制台转储许多错误

尝试在OSX 10.6.8，Qt 4.7：

下使用QFileDialog 
QFileDialog *dialog = new QFileDialog(0,tr("Load Band Recordings"),qbh,tr("Wave Files (*.wav)"));
dialog->setFileMode(QFileDialog::ExistingFiles);

if (dialog->exec())
{
QStringList fileNames;
    fileNames = dialog->selectedFiles();
    qs = fileNames[0];
}
else
{
    return(0);
}

它可以工作，但很多错误都被转储到控制台：

文档说提供父窗口小部件;似乎并不重要。

任何人都知道如何正确使用OSX下的Qt 4.7 QFileDialog类，以便它不会呕吐错误到控制台？

顺便说一下，文件和目录对话框的静态版本和构造版本都是这样做的。我在Qt论坛上问过，但没有得到答复。希望有人在这里找到它。
