Sorry about that. I am also reading bugs@gnus.org via the nntp gateway
and forgot to add a Cc-header. BTW, your Cc-header did not look good:

Cc: =?iso-8859-1?q?Bj=F8rn_Mork_<bmork@dod.no>, __bugs@gnus.org,
   __bug-gn?=.=?iso-8859-1?q?u-emacs@gnu.org?=

I guess this is the same problem you demonstrated in a previous
example. Never seen Gnus behave as bad as this before, though...

I am no expert on this, but trying to read RFC2822 and RFC2047 makes
me think that Simon is right. A 'quoted-string' is a 'word', and may
as such be replaced by an 'encoded-word'. The DQUOTE is part of the
'quoted-string' and should therefore be encoded with it.

So the proper way to encode

  From: "Bjørn Mork" <bmork@dod.no>

would be

  From: =?iso-8859-1?q?=22Bj=F8rn_Mork=22?= <bmork@dod.no>

I guess. An example of proper handling of a 'quoted-string' in RFC2047
would have been nice. But as far as I can see, this is the only way
you can do compliant encoding without losing any information.
