Problem is I can't reproduce the bug with your commands either 
(executing them as a regular user):

(david at austin:~)$ dd if=/dev/zero of=/tmp/foo bs=1k count=1024
1024+0 records in
1024+0 records out
1048576 bytes (1.0 MB) copied, 0.0060463 seconds, 173 MB/s
(david at austin:~)$ /sbin/cryptsetup luksOpen /tmp/foo /dev/mapper/_tmp_foo
Enter LUKS passphrase: 
/tmp/foo is not a LUKS partition
Enter LUKS passphrase: 
/tmp/foo is not a LUKS partition
Enter LUKS passphrase: 
/tmp/foo is not a LUKS partition
Command failed: No key available with this passphrase.

(david at austin:~)$

Are you able to reproduce the error with the version of cryptsetup that 
is currently in unstable?
