Thank you for trying to find a solution for the ffprobe error.
With this patch, text attachments are no longer shown as "text"
but as "none" and ffprobe outputs a warning:
Stream #0:9: Attachment: none
Metadata:
filename : .....
mimetype : text/plain
Unsupported codec with id 0 for input stream 9
Regards,
sw
