Perhaps it's a GNU/Linux specific bug, but I can reproduce this with Emacs
22-28. It worked with Emacs 21. standard-display-table is nil before
invoking describe-display-table, and somehow becomes populated when
discribe-display-table is invoked from a non-byte-compiled file, but not
when it is invoked from a byte-compiled file. A simple workaround is to
(require 'disp-table).
