The following crash message appeared when using the Pencil tool to draw a white line of width 4 over an existing item on the left edge of the screenshot. The screenshot was replaced with a red "X" in the graphics control.
I drew a very short stroke from within the editor near the left edge, moving my mouse to outside of the editor. I was not able to reproduce it - fuzzing may help, perhaps?

Taking another screenshot of the failure worked:
