having GTK messages from on a Qt application may only be attributed to the widget style as default from the DE environment in use (eg. gnome, xfce, etc.)

please go to menu Help > Configure... > Options > "Custom style theme" and choose anything else but the "(default)" or "Gtk+" for that matter ... set this style to "Fusion" which is my favorite and the one shown as of the official screenshots ;)

and while you're at it, make sure you keep "Use native desktop environment dialogs" to OFF (unchecked).

hth.
