1.2pre17 scp Input/Output error

[Berend De Schouwer]

Under OpenSSH 1.2pre17 I can duplicate and Input/Output error for scp:

Conditions:
pc36 is a RH6.0/i386 box.
abc.co.za is a RH5.2/i386 box. (private network)
openssh 1.2 pre 17 on both boxes.
Line between them is a 128k leased line.  It works between two 10baseT
machines.
If the scrollbar is active, the scp fails, if it isn't active, scp
works.  Note that without the scrollbar, the file gets there and is
valid.

I can try for an strace, but I'd rather not flood the mailing list. 
Also, server or client?  I've attached scp -v info because its rather
small, but useless.
