Hi Gennady and Hua,

Both confirmed.  David, do you have any outlook about this problem?  It
seems that gs 9.27 is incompatible with preview-latex when the default
face has non-trivial foreground color.
When the preview fails and I right-click the "do not enter" sign to
select "View error", the *Preview-Ghostscript-Error* buffer pops up and
shows the error quoted at the last of this message.  It tells that
"GS_PDF_ProcSet" caused the error and I found that the official
ghostscript document says "We eliminated GS_PDF_ProcSet" in [1].

Best regards,
Ikumi Keita
