Image Occlusion not working after use of pencil feature

[andrewmathias8]

Problem description

I inserted an image from my downloads in order to occlude certain parts of it (this always works fine). However, after using the "pencil" feature to write over the image, anki gives me an error message (copied below) when I try to create the cards by pressing "hide all, guess one". I believe that this is the issue because when I replicate the process without using the pencil feature the issue does not occur.

I too received the same error only when using the pencil tool.

I've got a similar error message when I tried to edit a card using the pencil tool as well:

Thanks for the detailed reports guys! It's much appreciated I was able to reproduce the issue locally and will look into it.

Fair warning, however: There is a good chance this is not solvable without updating to a newer version of SVG-Edit, and unfortunately that might not be feasible to do. But I will see if I can find a solution.
