It looks like you're coming up against this XFree86 revision 3.13:

  http://cvsweb.xfree86.org/cvsweb/*checkout*/xc/lib/X11/OpenDis.c?rev=3.13

which was in response to this bug:

  http://bugs.xfree86.org/show_bug.cgi?id=40

The part that's bothering you is just a small part of the patch, with
a comment that says "sanity check". Most of the changes check that the
server message was long enough, to prevent operating on uninitialized
memory, but this is just saying that the server returned too much data,
is what it looks like to me.

Perhaps we could make this just a warning?

In any case, would you please file a problem report (with NetBSD)?  Even
if the fix turns out to be that simple, we'll still need a record for the
upstream maintainers.
