Journal probleme avec kmail + app window maker

je viens de passer de debian stable a testing. tout c'est presque bien passe. juste un petit probleme de lilo tout pete sinon ca va.
sauf que kmail crash : quand je clique sur un de mes dossiers de mail l'application crash, voici ce que j'obtiens :

---------------------------FIN--------------------------------------

donc voila je peut p lus lire mes mails avec kmail, c'est pas tres pratique.
Est-ce que quelqu'un a deja eu ce probleme ? comment puis je resoudre ca ?

Et sinon j'avais cru voir passer en news sur linuxfr quelque chose a propos d'une application de jauge pour la batterie d'un portable pour window maker mais je n'arrive pas a retrouver l'article en question quelqu'un pourrait il m'aider a le retrouver ??
merci pour tout
