Thank you for a valuable report.  It seems that the Ghostscript
developers injected some change incompatible with preview-latex into gs
source, and that change was incorporated into the ghostscript binary
distribution of your package manager (Debian?).  I tried both gs 9.28
RC4 and the latest git repository, and ended up with the same result of
yours:

I have no workaround for this trouble now.  Please consider reverting
the recent gs update if you can.

I'll report this issue to gs-devel list.
