Iv also tested KAS on 1.0 on a new game, and have had no crashes or unexpected bugs. the only thing (as Eurofighter13 mentioned) I have noticed is that the containers will not fit correctly, but I have manage to get one to stick upside down to a normal connection point, and just flip it 180 degrees. I was then able to use them as intended. Struts, Pipes, Winches and grabbing/Placing all works perfectly.
