[O] New bug in org-agenda?

[Richard Stanton]

Using Org mode version 9.2.1 (9.2.1-33-g029cf6-elpaplus), I get an error 
message when I run org-agenda:

Debugger entered--Lisp error: (error "Wrong number of arguments")
  propertize("WAITING" nil face org-warning)
  org-agenda-get-restriction-and-command(nil)
  org-agenda(nil)
  funcall-interactively(org-agenda nil)
  call-interactively(org-agenda record nil)
  command-execute(org-agenda record)
  execute-extended-command(nil "org-agenda" #("org-agenda" 0 1 (fontified t) 1 
2 (fontified t) 2 3 (fontified t) 3 4 (fontified t) 4 5 (fontified t) 5 6 
(fontified t) 6 7 (fontified t) 7 8 (fontified t) 8 9 (fontified t) 9 10 
(fontified nil)))
  funcall-interactively(execute-extended-command nil "org-agenda" 
#("org-agenda" 0 1 (fontified t) 1 2 (fontified t) 2 3 (fontified t) 3 4 
(fontified t) 4 5 (fontified t) 5 6 (fontified t) 6 7 (fontified t) 7 8 
(fontified t) 8 9 (fontified t) 9 10 (fontified nil)))
  call-interactively(execute-extended-command nil nil)
  command-execute(execute-extended-command)

This has only started in the last few days and my init.el file has not changed, 
so it seems to be something in the latest update.
