[SOLVED] gnome-control-center crashes

Hello,

I have an up-to date arch installation, with an Geforce GTX 750 TI and the nouveau driver. I'm using gnome on wayland.
Since some weeks I get the following message when starting the gnome-control-center:

$ gnome-control-center 

(gnome-control-center:15142): Clutter-Gtk-ERROR **: *** Unsupported backend.

journalctl says to this:

systemd-coredump[15271]: Process 15265 (gnome-control-c) of user 1000 dumped core.

If I start it with

CLUTTER_BACKEND=wayland gnome-control-center

it works fine.
I use gdm and I have not uncommented any line in /etc/gdm/custom.conf - it's the file that comes with gdm.

glxinfo says:

$ glxinfo |grep -i opengl
OpenGL vendor string: nouveau
OpenGL renderer string: NV117
OpenGL core profile version string: 4.3 (Core Profile) Mesa 17.3.0

OpenGL extensions:

OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10

Any ideas?

//EDIT:
Solved. The user hat a file ~/.pam_environment with the following code n it:

CLUTTER_BACKEND=x11

deleting it solved the problem.
