I have used 

ii  x11-xserver-utils                 7.5+1                        X server utilities

ii  xserver-xorg                      1:7.5+5                      the X.Org X server

now for a week without crashes so I am very confident that it is the
new version 2:1.7.6-1 that causes the problems.
