the trash bin on my PI was getting full so I did a search and came up with this rm -rf /mnt/share/.Trash-0/files where my trash bin is for the sabnzbd installation this because the trash bin is on a samba share usb drive if yours is not .
Then rm -rf /home/YOURUSERNAME/.local/share/Trash/files or current user rm -rf ~/.local/share/Trash/files/*
Then rm -rf /home/YOURUSERNAME/.local/share/Trash/files or current user rm -rf ~/.local/share/Trash/files/*
