[SOLVED] Qt apps: Failed to load module "xapp-gtk3-module"

I have installed arc-gtk-theme and applied it by modifying gtk2 and gtk3 configuration files. In order to have the same look for Qt apps, I installed qt5-styleplugins and set the variable QT_STYLE_OVERRIDE=gtk2. Now, whenever I run a Qt app, it spits a message:

Gtk-Message: <timestamp>: Failed to load module "xapp-gtk3-module"

The massage says that it can't find xapp-gtk3-module, but when I echo GTK_MODULES, I do see xapp-gtk3-module.

$ echo $GTK_MODULES
canberra-gtk-module:xapp-gtk3-module

Although Qt apps open fine and have GTK look, the message bothers me sometimes since I do have xapp-gtk3-module. I could not find a definitive solution to fix this on the internet. Is this fixable?

It's a harmless log message which will go away the next time the xapp package is updated (probably 2.0.7), the module only supports gtk3.
