I added some images and with the Audio Tags selected by default, if I select "suffix only", the program crashes. I have tried this for 10 times. My os is Debian Testing 64bit
The product is wrong, this is not about the website.
Moving to the correct product.
Changing product again, because this belongs to the http://goodies.xfce.org/projects/thunar-plugins/thunar-media-tags-plugin.
With thunar-media-tags-plugin 0.2.1 on Debian 9 (stretch), this works.
I can't reproduce, closing, if this is still a issue for you, please reopen.
