Pdf files renames and loses it's extension when opened from k9mail

Hi all.

  1. Get email with a pdf attachment
    2 open this attachement with any app
    3 see what filename is opened (it’s generated randomly?)
    4 try to send it via telegraam
    5 see you’ve send not pdf but a file with a random name without extension

Is it a bug ?

No, it is the way K-9 sends the intent. It is supposed to include the actual file name in the intend, but somehow this does not work for some users. @cketti has explained how it works in another thread. (you should be able to find it through the search)
