Thanks for your time Chris and Sebastien. Here is the new gdb file and my Xorg log. Unfortunately I don't have Karmic installed on the nx servers I have and as they are calculation servers used by 5-6 users I don't want to install a development version. I do have a spare machine which I will try to install Karmic and test this on but this will take time.
