I want to build a GUI for Gnome (using guile-g-golf (and gtk)).

When under Gnome my small "Hello World" (from the manual example
script) window shows up.

When under KDE (Plasma) nothing shows up but errors in the terminal :

    $ guix shell guile gtk guile-g-golf -- ./hello-world
    (guile:10978): GLib-GObject-WARNING **: 12:19:06.388: cannot
    register existing type 'GdkPixbuf'
    (guile:10978): GLib-GObject-CRITICAL **: 12:19:06.388:
    g_type_add_interface_static: assertion 'G_TYPE_IS_INSTANTIATABLE
    (instance_type)' failed
    (guile:10978): GLib-GObject-CRITICAL **: 12:19:06.388:
    g_type_add_interface_static: assertion 'G_TYPE_IS_INSTANTIATABLE
    (instance_type)' failed
    (guile:10978): GLib-CRITICAL **: 12:19:06.388: g_once_init_leave:
    assertion 'result != 0' failed
When using g-golf make sure to disable grafts:

   guix shell --pure --no-grafts \
     guile guile-g-golf gtk@4

The same problem was found in guile-gi first:
