Alan, I've tested your instructions exactly on an Ubuntu Ibex 64-bit system and I do not see any segmentation fault with tkdemos.tcl. This is with tk version 8.4.19. I do see a segmentation fault if I try plserver -f tk03.
By the way tk01, tk02 and tk03 do not work correctly for me. Is this an itcl issue? If so we should disable these for the case without itcl. As an aside, why do we have copies of all the x??.tcl examples in the tk examples directory? As far as I can see these are identical to the tcl versions except that the tcl versions have been updated and the tk versions are rather old.
