I installed a game, and then decided to erase it. I sent it to the recycle bin, but I was unable to delete it completely (Permission denied). When I moved it back to the desktop, a copy remained in the recycle.
I sent it back to the bin, and back to the desktop; so I ended with 2 copies of the file in the bin, and one on the desktop.
Finally I noticed that a file inside the game was protected. I changed the permission settings to the desktop copy and I was able to erase it completely, but I was not able to change the permission settings on the 2 copies I still have in the bin (the backend do not support the operation)

I just want to empty the recycle bin!
