UEFI partition labeled incorrectly as "Linux filesystem"

[Nick B.]

On a fresh install of 14.10 server version the UEFI partition the installer created (mounted on /boot/efi) is incorrectly set as 0x8300 Linux filesystem. The partition is actually a FAT partition and should be 0xef00.

mount says it's mounted as vfat:
/dev/sda1 on /boot/efi type vfat (rw)

but gdisk says it's a Linux partition
GPT fdisk (gdisk) version 0.8.8

Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.
Disk /dev/sda: 488397168 sectors, 232.9 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): D87C8175-4EB2-4DA4-A646-D4CD6A8B90AF
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 488397134
Partitions will be aligned on 2048-sector boundaries
Total free space is 2349 sectors (1.1 MiB)

Oops. I mean it should be 0xef00 for EFI System.
