Upon closer examination, I may have found part of the problem:  For me,
the above semilogy command causes gnuplot to create postscript file that
has *two* "showpage" commands in it.  For some reason this confuses
epstopdf, but it does not seem to bother dvips.

If I manually edit the eps file, and remove the first showpage (but not
the second), I no longer have the disappearing line problem with pdflatex.

Thanks for all your help!
