Hello, sorry to bother you.
I ran into a bug in parted this morning when trying to label an encrypted partition. Does parted support LUKS partitions?
Thanks for your time.
Details:

version: 3.2
error message: Assertion (disk != NULL) at ../../libparted/disk.c:1598 in function ped_disk_get_partition() failed.

backtrace:
(parted) name Encrypted
Error: /dev/sda3: unrecognised disk label
Error: Expecting a partition number.
(parted) name 3 Encrypted                                                
Error: /dev/sda3: unrecognised disk label

output of command `parted` told me to run:
