quake4 1.4.2 crash

[ArtX]

Ciao
uso debian testing e ho installato correttamente quake4 con la patch 1.4.2.
Il gioco parte perfettamente ma quando carica una partita qualsiasi, (ho provato sia nuova partita che da un salvataggio che avevo su win), il gioco mi crasha e torno al desktop.
Ecco il problema:

Qualcuno ne sa qualcosa?
Centra per caso con qualche incompatibilità dei pk3?
grazie
