Well, I have found a few bugs that will 100% of the time crash premiere.
If you are messing with the position of a clip, like moving a keyframe and autosave kicks in it crashes every time.
If you his save at the same time it was going to autosave it crashes every time.
If you are typing in the caption window when it autosaves it crashes every time.
Also autosave doesn't work the same anymore. It apparently waits until there is a lull in your activity. So autosave even though you set it to every 3 minutes for instance wont happen for 10+ minutes. You may see the autosave window pop up, but if you hit a keystroke it cancels out. Frustrating....
