À défaut de tout cela, voici la fin d'un log de la commande "strace
amarokapp".

Et d'autre part, pas d'erreur de mémoire détectée par memtest86+.
Se peut-il que certaines librairies installées soient incompatibles sans
que cela soit détectable à l'installation ? La réponse est certainement
oui, mais j'aimerais pouvoir faire quelques tests. Comment savoir de
quelles librairies dépend un package (pas un binaire, ça, je sais) ?
