Subject: Character of Death locks one out of all newsgroups
Date: Sat, 27 Dec 2008 05:25:01 +0800	[thread overview]
Message-ID: <87bpuytys2.fsf@jidanni.org> (raw)

One bad character locks me out of all newsgroups... until when, one
doesn't know. Great denial of service attack.

Debugger entered--Lisp error: (error "Can't rfc2047-encode `\x2563d\x2587c \x256cf\x7ecf'")
  signal(error ("Can't rfc2047-encode `\x2563d\x2587c \x256cf\x7ecf'"))
  error("Can't rfc2047-encode `%s'" "\x2563d\x2587c \x256cf\x7ecf")
  rfc2047-encode(5 10)
  rfc2047-encode-region(1 12)
  nnrss-mime-encode-string("Re: \x2563d\x2587c&#20146;\x256cf&#32463;&#21382; 3")
  nnrss-check-group("BDSM \x25322\x25cf0\x25d37\x268a2" "")
  nnrss-request-group("BDSM 一般討論" "" nil)
  gnus-activate-group("nnrss:BDSM 一般討論" scan)
  gnus-get-unread-articles(nil)
  gnus-group-get-new-news()

Input was http://www.bdsm.com.tw/phorum/rss.php?1

If you can't rfc2047-encode something, then put a "bad character
character" in its place.

Firefox shows the line as
Re: 我的&#20146;身&#32463;&#21382; 3
That would be still better that bombing out too.

Anyway, I had to use
C-k runs the command gnus-group-kill-group
to be able to use
g runs the command gnus-group-get-new-news
ever again. Else one must use many
M-g (translated from <escape> g) runs the command gnus-group-get-new-news-this-group
If I dare use
c runs the command gnus-group-catchup-current
I just get

  call-interactively(gnus-group-catchup-current)

Who knows why it must encode things just to mark them as read.

I wonder how I ever can read this group again?
