Not sure why, Daniel, but it seems I'm your nemesis
I have an architects floorplan as a background image in a big SH3D file I've been working on. It seems that your SVG Tuner really doesn't like that image. It just never finishes exporting after many minutes. It works in a few seconds without the plugin. If I disable the background containing layer, it works OK with your plugin, so it seems specifically linked to that background image. Last symptom is if I cancel a stalled export, then try a second export, nothing happens after selecting the file name. It would suggest something went badly wrong, and the function is no longer callable somehow.
Nothing in the logs from your autologger plugin.
Amazing job of pumping out these plugins by the way.
