Description xorg 2006-12-02 17:55:13 UTC 
X (with composite extension enabled in xorg.conf) crashes when e.g. glxgears terminates, because __glXMesaScreenDestroy tries (at xf86glx.c:284) to access mesaScreen->xm_vis[i] for the last visual too, which isn't a mesa visual though, but has been created by the composite extension.
