Protocol error's with 2.1.0p2

	I'm getting "Protocol errors" when trying to scp files from my
laptop to my desktop (only when trying to scp root at laptop:/path/file, not
vis-vis).  See screen dump's at end of e-mail for exact details.  The most
confusing thing about this problem (to me anyway), is that this is a
one-way problem.  I can log into the laptop and scp files down from the
desktop no problems.

	System software spec's.

Desktop: RedHat 6.2, fairly vanilla - 2.2.15 kernel compiled with fairly
		standard options, extra packages and such, but no real
		"changes" per-se as far as packages, just additions.

Laptop:  	RedHat 6.2, very vanilla - stock kernel, a few extra packages,
			and not much else.

OpenSSL version: 0.9.5a
OpenSSH version: 2.1.0p2 

	Both packages were built from SRPM's on the desktop machine.  I
have also gone through and verified that all lib's and versions reported
by ldd /usr/bin/scp and ldd /usr/sbin/sshd are identical.  Config files on
both boxes match as far as options, and with the desktop, and I have no
problem scp'ing with any other box I use openssh to communicate with
(although they are mostly openssh-1.2.x flavor's), this is isolated to
scp'ing with the laptop.

	I've also stripped openssh from both boxen completely (even rpm
-Rf ~/.ssh), and re-installed, to no avail.

	Anyway, long and short of explanations above, I have some small
amount of clue, and have done as much homework on trying to figure this
out as I know how to do.  Obviously I don't know everything, or I'd have
this working by now though. :)

If what they've been doing hasn't solved the problem, tell them to do
something else.
