I was puzzled by that comment at first, but then I remembered the
nopstricks package option. Sure enough, the problem still exist when
pstricks isn't loaded.
I have tracked it to this part of pst-pdf.sty (here copied from the
Prevent multiple test-wise setting of table contents by “tabularx”.
If I'm reading everything correctly, pst-pdf redefines tabularx to
behave like tabular in DVI mode (which would be when it is extracting
graphics on the latex, as opposed to pdflatex, run). When I make a local
copy of pst-pdf.sty and comment out these four lines, the problem goes away.
Looking a little deeper, I think the issue is that threeparttable hooks
into tabularx, but when pst-pdf redefines tabularx there is no way for
threeparttable to compensate.
I'll have to think about how to handle this -- perhaps I'll post it to
comp.text.tex, since it involves a non-PSTricks-related package. Also,
doesn't pst-pdf's redefinition here prohibit the use of tabularx within
