Public bug reported:

Binary package hint: xorg

With the Lucid LiveCD Ubuntu/Xubuntu i386 images (2010-03-04), xserver
crashes on all but the first start with a seg-fault in libint10. In
other words, after stopping gdm ("sudo stop gdm") and trying to start it
subsequently ("sudo start gdm"), this error occurs:
