[Gcompris-france] problème avec SVG, gcompris 12.01, archlinux 3.2.5

[t.q]

Bonjour,
J'ai le traditionnel "xyz.svg manquant.

Debug:
** Message: Binary relocation enabled

** (process:2547): WARNING **: exec_prefix /usr/bin

package_data_dir         = /usr/share/gcompris/boards
package_skin_dir         = /usr/share/gcompris/boards/skins
package_menu_dir         = /usr/share/gcompris/boards
package_locale_dir       = /usr/share/locale
package_plugin_dir       = /usr/lib/gcompris
package_python_plugin_dir= /usr/share/gcompris/python
user_dir                 = /home/spira/My GCompris
gcompris: gc_locale_set 'fr_FR.UTF-8'


Infos:
    Config dir '/home/spira/.config/.gcompris'
    Users dir '/home/spira/My GCompris'
    Database '/home/spira/.config/.gcompris/gcompris_sqlite.db'
gcompris: Database /home/spira/.config/.gcompris/gcompris_sqlite.db opened
...
gcompris: Loading image 'computer.svg' returned a null pointer
etc.

Les fichiers svg sont bien dans /usr/share/gcompris/boards

recherche des librairies svg:
gdk-pixbuf-query-loaders | grep svg
"/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.so"
"svg" 2 "gdk-pixbuf" "Scalable Vector Graphics" "LGPL"
"image/svg+xml" "image/svg" "image/svg-xml" "image/vnd.adobe.svg+xml" 
"text/xml-svg" "image/svg+xml-compressed" ""
"svg" "svgz" "svg.gz" ""
" <svg" "*    " 100
" <!DOCTYPE svg" "*             " 100

La librairie est bien là: -rwxr-xr-x 1 root root 9664 30 janv. 22:49 
/usr/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.so
paquet: /usr/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-svg.so 
appartient à librsvg 2.34.2-3

ldd /usr/bin/gcompris | grep pixbuf , donne:
pixlibgdk_pixbuf-2.0.so.0 => /usr/lib/libgdk_pixbuf-2.0.so.0 (0xb717d000)

Que dois-je faire ?
Merci.

Jo.
