So it is three of you, and all on AMD64s.  This *is* strange.  If anyone 
of you feels adventurous, it'd be great if you could investigate that 
further and try to pin down where the problem is.

Can you confirm that it is confined to the tree view and menu demo?

As I said before, we are working on a port to cells3 and cffi-darcs, 
which might solve things *if* it is a cells or cffi issue.

If it is a gtk thing we might need to create a work around.  I'd ge most 
grateful if anyone of you 64bit guys can dig deeper here, since I cannot 
reproduce the problem on my four year old machine.

I'll be happy to respond to questions or help with the general 
understanding of gtk/cells/cells-gtk.

Thanks for pointing it out.  I committed that to CVS yesterday.  Somehow 
my gcc silently does the right thing.  Maybe they changed it to be more 
picky in the current or 64bit version.

Best,
Peter
