Yes, i'm using 2.4.4 form natty repos.
$ dpkg -l | grep uck
ii uck 2.4.4+repack0-0ubuntu1
Anyway as Wolf Geldmacher said above probably is not related to UCK but to X,
because i tried to customize a livecd image without UCK, using commandline, and I got same crash.
Probably a full backtrace of X could help.
