copy_trailer_attrs is not called by anything in preview-latex, so it
would appear like your version of dvips is incompatible with your
version of Ghostscript, or that Ghostscript is inconsistent on your
system.

Another possibility is that the apparent hack of copying GS_PDF_ProcSet
(I don't remember right now what this is supposed to do) no longer works
for some reason.
