Crach signal 11 SIGSEGV

Bonjour, tout le monde. Voila mon problème je doit "déboguer" une grosse application qui tourne sur Suse 8.1 et utilise l'IDE KDevelop avec la bibliothèque graphique Qt 3.2.

Je sais que ce signale correspond a une erreur de segmentation et que le programme écrit la ou il n'a pas le droit ou dépasse un tableau. j'ai récupérai un "rapport de bog" seulement je n'arrive pas a l'interpréter(comprendre), si vous pouvais m'aider.
c'est apparemment, "gdb" qui est intégré à l'API qui génère ce rapport.

voici le rappport:
