I can't reproduce this. 

GNU Emacs 21.4.1 (i386-redhat-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2006-03-07 on hs20-bc1-6.build.redhat.com
up-to-date
up-to-date
up-to-date

The bug report used 21.3, I tried it with 21.4. AFAIR the only
difference between the 2 is some security bug that had nothing to do
with VC.
