Great, thanks Christopher. Wow, nice going Ricardo, that fixes the
issue!

I ran:

  $ find ~/.guix-profile/ -type d -wholename '*lib/gdk-pixbuf*'
  /home/ben/.guix-profile/lib/gdk-pixbuf-2.0
  /home/ben/.guix-profile/lib/gdk-pixbuf-2.0/2.10.0
  /home/ben/.guix-profile/lib/gdk-pixbuf-2.0/2.10.0/loaders

and then:

  LD_LIBRARY_PATH=/home/ben/.guix-profile/lib gnome-shell

after which I could then select "Activities" and "Show Applications"
without any problems.

As you suggested was able to make the workaround persistent with:

  $ echo "LD_LIBRARY_PATH=/home/ben/.guix-profile/lib gnome-session" > ~/.xsession
  $ chmod a+x ~/.xsession

Is there a way to fix this more permanently in Gnome?

Regards,
Ben
