You have the same configuration as Helge Kreutzmann, can you please havea look at http://bugs.debian.org/387917 and follow instructions there?
I am still getting the X crash with exp2, despite using -option to try to kill all previous options, followed by the options I actually want.
I have an iMac iSight G5 (PowerMac12,1), so a different configuration to Helge, and I am using GB rather than DE.
Ok, then you may put xkb-data on hold, because these patches have been merged upstream and I am willing to upload into unstable very soon to have broader testing.
Oh! Not sure which patches you mean have been merged upsteam, because if it includes the xkb-data that crashes my machine, I obviously would not think that a good idea.
Tim.
