Is this the backtrace you get?

Debugger entered--Lisp error: (file-missing "Opening input file" "Decryption 
failed" "")
  signal(file-missing ("Opening input file" "Decryption failed" ""))
  epa-file--find-file-not-found-function()
  run-hook-with-args-until-success(epa-file--find-file-not-found-function)
  find-file-noselect-1(#<killed buffer> "/tmp/foo.gpg" nil nil "/tmp/foo.gpg" 
(24379592 66306))
  find-file-noselect("/tmp/foo.gpg" nil nil t)
  find-file("/tmp/foo.gpg" t)
  funcall-interactively(find-file "/tmp/foo.gpg" t)
  call-interactively(find-file nil nil)
  command-execute(find-file)

I'm not sure whether there's any way for epa to know at this point
whether the failure was due to a wrong password or something else, so
I'm not sure a user-error would be appropriate.  Anybody know?
