I can't reproduce the undo crash, but I do get a crash with the following steps:
- Select Pencil tool
- Press and hold left mouse button, and then draw
- While still holding the left button, press and hold the right mouse button
- Release the left button, but continue to hold the right button
- Move the mouse anywhere and then release the right mouse button
