It's due to this change in the Emacs trunk:

2008-04-05  Stefan Monnier  <monnier@iro.umontreal.ca>
[...]
	* gnus-fun.el (gnus-display-x-face-in-from): Remove unnecessary use of
	default-enable-multibyte-characters.

I think it is the right thing but it causes the `uncompface' function,
which `gnus-display-x-face-in-from' calls, to generate a multibyte
temp buffer and to break binary data that the external icontopbm
program generates.  I've fixed it in the Emacs trunk so as to make
that temp buffer unibyte as follows:

*** compface.el~	Tue Jan  8 21:51:25 2008
--- compface.el	Tue Apr  8 02:53:53 2008
