Not sure since when, but Audacious can not add Folders anymore, nothing happens when you browse to the desired folder and try to add it (from within audacious, click FILE+ then click ADD FOLDER, then browse, then try to validate it does nothing). Adding single file works though.
Don’t see relevant error in terminal, only thing I see is kf.kio.core: "Could not enter folder tags:/." but I think it is just a harmless log output.
Thats a theme issue,if you switch to breeze for example,the icon will be displayed normal, I have arc dark and have the same issue but i don’t mind it.
