That one worked...perhaps I had some cruft in my tree :-/.
This line is new in the output:
(gimp-2.6.exe:52): Gimp-Display-CRITICAL **:
`GIMP_IS_IMAGE (shell->display->image)' failed
but doesn't seem to be critical.
Card is a 9800 GeForce GTX, 190.18 drivers.
Running the suite again, it seems to work fine. Photoshop had that
failure we discussed on IRC, but it's a subtle race condition
unrelated to your patch. I'm working on that now.
