coreutils version 9.1-1 on Debian testing, but also exists in previous 
versions.


Example:

stat -f  /dev/disk/by-uuid/6abaa68a-2670-4d8b-8d2a-fd7321df9242
  File: "/dev/disk/by-uuid/6abaa68a-2670-4d8b-8d2a-fd7321df9242"

blkid /dev/sdb
/dev/sdb: UUID="6abaa68a-2670-4d8b-8d2a-fd7321df9242" 
UUID_SUB="d15f1846-8f18-4ba0-9e2a-a6aaa7bbf83b" BLOCK_SIZE="4096" 
TYPE="btrfs"


Not sure why the reported fstype is wrong but obviously it is a bug.


TIA
