I was seeing the above error twice in the terminal whenever I opened Inkscape from the command line (Linux, Inkscape 1.3.2, but I've been seeing it since soon after 1.0), even when not using the extension. It was always annoying, but didn't cause problems so I never got around to reporting it.
Anyway, I forked this #repository to fix it, at nms-scribe/slick-fork, it's only two lines to fix it. The solution was to change the gui_text = "" attributes in the .inx file to gui_text = " ". If you'd prefer a pull request, I can make one.
