This is it!

The linked channels!  I started using linked channels in ardour to do 
groupings, because when I use groupings on the mixer, the movement would 
sometimes stick - same feeling as the "Fighting controller" bug we had a 
while back.  When I disable the linking of channels in Ardour, and do it 
on my mixer, the errors go away!!!  Movement is just sticky now, but 
that is another problem.

I am sure that you could now recreate the problem...  I'll still see if 
I can hack at the code, but what may be a week for me could be a few 
minutes for you.  Helps if you know the code!

Thanks for your efforts,
