I haven't done anything. It was my Distro [yes, I should use a
different one, but still some key packages missing] :-)

I'm unsure on what to do with this, probably will just unset it
somewhere:

I'm using Guix on top of Ubuntu. Error appears when using programs
installed from Guix. After some investigations, I found out this
environment variable is set in:

/etc/X11/Xsession.d/51gtk3-nocsd-detect

      *)
          # not GNOME, and the user didn't specify GTK_CSD
          # themselves, so set it to 0
          if [ -z "$GTK_CSD" ] ; then
              GTK_CSD=0
          fi
          export GTK_CSD
          if [ x"$GTK_CSD"x = x"0"x ] ; then
              export
LD_PRELOAD="libgtk3-nocsd.so.0${LD_PRELOAD:+:$LD_PRE fi
          ;;

I'm currently using a non-GNOME windowing environment, so I'm in this case.

The library is this:

It should make some things nicer if you don't use GNOME. This seams to
be a hack. Do we need this library in Guix too, to get some decorations
back?
