Thanks for the report. I'm glad things are working for you on Emacs 26. However, I'll still look into your initial error because Emacs 24 is the specified minimum version. (And I really should add Emacs 24 to the Travis matrix to catch these issues.) -- You are receiving this because you are subscribed to this thread.
