It is defined as gnus-summary-pipe-output.

I spent some time with this.  By temporarily renaming my startup files one
by one I've narrowed it down a little more.  My .emacs seems to be OK.  If
I rename .gnus AND .xemacs-options I'm OK.  If I load either .gnus OR
.xemacs-options, I get 'Wrong type argument: stringp, nil'.  The backtraces
in either case appear to be identical except for the tmp buffer name.

I've been through both files and I don't see anything obviously wrong.  But
then, I don't really know what I'm looking for.

Backtrace with .gnus loaded follows.  I hope that's OK.
