slrn hangs on X-Face header

Hello,

I'm using slrn 0.9.8.1pl2.1 [2007-07-17] (Debian package build with
Thomas' script "build_deb_from_cvs.sh").  I encountered several
postings that let slrn eat all memory including swap until killed by
the kernel.  I noticed that all these postings have in common that
they contain an "X-Face:" header and when I remove this header in my
local news spool slrn can display these postings just fine.

An example for such a header:

X-Face: /#02M#7?aBv8;\1p(MfZIgg5-R^.<T%UtJ6@tef|[6ey^X<u@^;8.e$<=?utf-8?q?i*fEQyPiaahnMV=0A=09saSMj2Jd=27=23-!g=25Q=279=3BSE=5Ee/X=60VgPp?=

 =?utf-8?q?54=5BjP=27=3A=0A=09fO?=

Is this a bug or a misconfiguration on my part?

Greetings,
Martin
