I was just reading over the CLIM spec, and apropos of this function, it states that there should be a default to the ARC-DRAWER keyword argument.
"If arc-drawer is unsupplied, the default behavior is to draw a thin line from the ``from'' node to the ``to'' node using `=--cldraw-line*."
But what's checked into the CVS now doesn't have that, causing crashes if it's omitted. I think some simple default to DRAW-ARROW* should work, but I'm too abysmally ignorant of CLIM to propose a patch myself.

Maybe something like this (untested):
#'(lambda (stream from to from-x from-y to-x to-y) (declare (ignore from to)) (draw-line* stream from-x from-y to-x to-y))
McCLIM's FORMAT-GRAPH-FROM-ROOTS, like the above function, currently ignores :ARC-DRAWING-OPTIONS.
