two xfaces causes emacs-20.2 to segfault

[Vladimir Volovich]

Hi,

I'm sorry if this was already discussed in this mailing list. If the
message, contains two X-Face headers, this causes the Emacs-20.2 to

this mailing list caused the above behavior for me:

Since the procmail workaround was so easy I figured I ought to forward
it on.  The formail program that is distributed with procmail has an
option to uniqify headers (eg stripping all but the first or last
occurrence of the given header.  I put this in my .procmailrc:

:0 fw
|formail -u X-Face:

and things seem to be much better now.
