Mails to Harven bounce back with the error:

  <harven@free.fr>: host mx1.free.fr said: 550 5.2.1 This mailbox
    has been blocked due to inactivity (in reply to RCPT TO command)

So I tried out your patch and it fails with:

  Debugger entered--Lisp error: (wrong-type-argument stringp nil)
    file-name-nondirectory(nil)
    doc-view-mode()
    doc-view-toggle-display()
    call-interactively(doc-view-toggle-display nil nil)

I don't understand how do you expect it to work.
