Good morning, After upgrading to notmuch 014 I am seeing the following messages appear in the messages buffer. error in process filter: byte-code: Wrong type argument: number-or-marker-p, nil error in process filter: Wrong type argument: number-or-marker-p, nil I am also getting a repeating message in the minibuffer (I think) which says something like "json read tail error". Sorry that I am not more specific as I use emacspeak and this message appears to repeat many times interupting speech so I am not 100% sure of what it exactly says. My gut feeling is that it is happening when notmuch is updating the database or something. Is this expected behaviour? It is particularly annoying for me as it sends the speech synth crazy and crashes it for a period of about 30 seconds. If it is expected then I will try and find a way to prevent emacspeak from trying to read it. Kind regards Bart -- Bart Bunting - Engineering Manager - URSYS 459-461 Parramatta Rd.
