Public bug reported: What I did to cause this:
Installed ubuntu using btrtfs root. Added a device with 'btrfs device add /dev/sda9 /' Balanced the file system with 'btrfs filesystem balance /' Tried to remove a device with 'btrfs device delete /dev/sda9 /'. Noticed that I got the error "ERROR: error removing the device '/dev/sda9'". (Unfortunately, I'm not sure how to get more information on the problem.)
