我正在Qt中编写一些代码，当我使用QColorDialog时，应用程序将冻结，并显示以下输出：
GLib-GObject-WARNING **: 10:53:36.573: cannot register existing type 'GtkWidget'
GLib-GObject-WARNING **: 10:53:36.573: cannot add class private field to invalid type '<invalid>'

我在一个空白项目中尝试了相同的代码，并且可以正常工作。我正在使用以下代码来显示QColorDialog：
QColor m_color;
m_color = QColorDialog::getColor(m_color, this, QString(), QColorDialog::DontUseNativeDialog);
我已经尝试清除QtCreator缓存以删除/home/user/.config/QtProject，并且已经尝试删除项目中的.pro.user文件
我试图在Debian 9和Linux Mint 19.1 Cinnamon上运行，同样的问题。
