Has anyone else ever experienced this?
This is Makulu KDE.
For some reason Dolphin has always shown two locations for Home/Root/Network/Trash, one of which was not accessible anyway. Previously I just dismissed this as one of the inevitable Linux quirks, but overnight these spare directories have multiplied into a complete family.

I've tried un-installing Dolphin, deleting whatever other references I could find for it and re-installing, but the result is the same. Have currently replaced it with Nautilus, although not ideal.
