Veuilez me dire quelle est ma faute merci d avance

je veut signaler que la fenetre et la liste s affichent mais cette dernière est vide
voici les erreurs signalées lors de l execution

j ai trouvé ma faute c est dans cette ligne
pColumn= gtk_tree_view_column_new_with_attributes("",pCellRenderer,"texte",1,NULL);

elle doit etre

pColumn= gtk_tree_view_column_new_with_attributes("",pCellRenderer,"text",0,NULL);

j espere que mon programme soit utile pour quelques uns.
