After a bit of testing I discovered that I can "fix" my problem by either
1. removing all custom-set-variables from the startup code,
2. toggling font-lock-mode off then on in a psgml-* buffer that does not
    display correctly, or
3. starting with --vanilla.

I believe this may mean that there is a memory corruption related to the psgml
regexps which causes the regexps test code not to be called for psgml files
(includes xml and html).  I have a number of custom-set-variables and
custom-set-faces defined for HTML mode; however, simply removing those from the
startup has no effect on the outcome.  leaving them in and removing all
custom-set-variables does appear to fix the problem.  I tried reinstalling (and
recompiling) the psgml package, but that did not help.
