I didn't have the shape selected before I ran the extension. I downloaded Inkscape just for this extension, so I expected it to use all the paths in the SVG I opened. I wasted a bit of time troubleshooting before realizing this. It might help to detect when nothing is selected and give a more descriptive error message.

FWIW I added a try/except to the line 632 (and 633) and got an error about the "SVG" not being valid. Both error messages seemed to indicate it was an issue with my SVG's encoding. Selecting the object with Inkscape first worked though.
