Probléme "Segmentation Fault"

Bonjour tout le monde :)

Je suis débutant dans le monde GTK et j'ai un problème qui freine depuis 2 jours dans mon projet GTK. J'ai, donc, décidé de vous en parler en espérant que vous aurez la solution ^^

J'ai créer un widget GtkMorceau personnalisé et je voulais créer un tableau de ce widget. Tout se passe bien, mais pour l'initialisation ça m'affiche un "segmentation fault".

Voici le code du widget "Morceau.c" :
