bug#21938: 24.5; PostScript Print Buffer fails on Agenda buffer

[sgeorgii .]

I launch emacs (-q switch makes no difference), open my .org file and
proceed as follows:

M-x org-agenda

a (agenda for current week or day)

menu "File" ->  "PostScript Print Buffer"

instead of printout of agenda on my printer I get the following error
in Backtrace:

Debugger entered--Lisp error: (wrong-type-argument listp org-priority)
  ps-face-attribute-list((bold . org-priority))
  ps-plot-with-face(78 82 (bold . org-priority))
  ps-generate-postscript-with-faces1(1 4783)
  ps-generate-postscript-with-faces(1 4783)
  ps-generate(#<buffer *Org Agenda*> 1 4783 ps-generate-postscript-with-faces)
  ps-spool-with-faces(1 4783 nil)
  ps-print-with-faces(1 4783 nil)
  ps-print-buffer-with-faces(nil)
  call-interactively(ps-print-buffer-with-faces nil nil)
  command-execute(ps-print-buffer-with-faces)


I have this error on both Windows and Linux hosts with emacs version
24.5. Emacs version 24.3 or earlier work just fine on same Windows and
Linux hosts.

I get this error with "PostScript Print Buffer". If I choose "File"->
""PostScript Print Buffer (B+W)" - this gives me printer printout all
right on all versions of emacs on both Windows and Linux hosts .

Any help?
