Raikkonen round the outside of a car exiting the pits and not yet up to speed. The outside of T1 becomes the inside of T2, so Raikkonen had every reason to try the move. Sutil didn't give him and room and there was a collision because of it. Webber steering into Barrichello at the start to try and bully him into not fighting for position is a bit different because it was done in a straight line and at high speed.
It was Räikkönen's fault clearly, he was way back at turn-in and just drove into Sutil's exit line, which was also the racing line. Sutil didn't drive over some ice cream and understeer into Räikkönen.
