This bug still exists in Arch Linux as of 9/2/2018. Gparted version is 0.31.0-1 and blkid version is 2.32.1 (as part of util-linux).
FWIW, I hit this bug after creating a ZFS Intent Log (ZIL) partition on my SSD root disk for a ZFS array of HDDs. The ZIL is partition 9. This is fairly serious bug for anyone trying to optimize a ZFS array using a small piece of an SSD that is otherwise used for other non-ZFS partitions. It renders gparted useless for that device. Here's some debug output that looks similar to previous comments in the bug.... sudo fdisk -l /dev/sda Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: 478CE577-056B-4DE2-BB0E-0D28A37F4223 Device Start End Sectors Size Type /dev/sda1 2048 206847 204800 100M EFI System /dev/sda2 206848 468991 262144 128M Microsoft reserved /dev/sda3 468992 167429602 166960611 79.6G Microsoft basic data /dev/sda4 167430144 168407039 976896 477M Windows recovery environment /dev/sda5 168409088 169330687 921600 450M Windows recovery environment /dev/sda6 169330688 202885119 33554432 16G Linux filesystem /dev/sda7 303548416 437766143 134217728 64G Linux filesystem /dev/sda8 571983872 959995903 388012032 185G Linux LVM /dev/sda9 959995904 976773119 16777216 8G Linux filesystem /dev/sda10 202885120 303548415 100663296 48G Linux filesystem Partition table entries are not in disk order. and the blkid output.... sudo blkid | sort /dev/mapper/vgs1-home: LABEL="HOME" UUID="274ffc71-601a-4346-92a2-b12b162047b3" TYPE="ext4" /dev/mapper/vgs1-KVM: LABEL="KVM" UUID="30786057-1854-4951-ab2c-fcbeed0ac296" TYPE="ext4" /dev/mapper/vgs1-swap: UUID="694fecbf-e63d-4f3d-b8ca-e34e28fb9dd6" TYPE="swap" /dev/sda1: UUID="AEF7-9E86" TYPE="vfat" PARTLABEL="EFI System Partition" PARTUUID="78db1804-fe44-49de-bc90-4c6f4d92b639" /dev/sda2: PARTLABEL="Microsoft reserved partition" PARTUUID="5d102957-ba80-4df7-94b7-e3e7fd3dc399" /dev/sda3: LABEL="WIN10" UUID="F050FDA050FD6E2A" TYPE="ntfs" PARTUUID="4580462c-87aa-4cb4-b8ae-28947d47e1e9" /dev/sda4: UUID="8208160E08160239" TYPE="ntfs" PARTUUID="a605a0fc-37a2-40b3-9036-2d203850ef46" /dev/sda5: UUID="96648D07648CEB77" TYPE="ntfs" PARTUUID="1cfe16fb-4211-4e9d-afaa-46febcf22375" /dev/sda6: LABEL="Mint 18.2" UUID="eb7c8e56-8914-4e0c-ae24-3da5ab7d7624" TYPE="ext4" PARTLABEL="Mint 18.2 Sonya" PARTUUID="2dc83abc-cfda-48e3-ac1a-aadacddeb75f" /dev/sda7: LABEL="Manjaro 17" UUID="96d61d3d-25e0-4d4e-a5b1-e35b3731c856" TYPE="ext4" PARTLABEL="Manjaro 17" PARTUUID="7ef8cc0a-7300-4934-9e55-666bebd9a80a" /dev/sda8: UUID="N31dEh-ZP4A-uxaL-aU9x-vEkl-Kw1H-7zO9g6" TYPE="LVM2_member" PARTLABEL="PVS 1" PARTUUID="fc1e4f3e-e49c-46ff-a73a-8206a47d3904" /dev/sda9: LABEL="NAS" UUID="721887637963356003" UUID_SUB="10629598274000407582" TYPE="zfs_member" PARTLABEL="ZIL" PARTUUID="3edafb8b-d13e-463a-a93b-cf961edb358b" /dev/sda10: LABEL="Man 17 Backup" UUID="bb77925d-0ce3-477b-aced-16ba3b7f4870" TYPE="ext4" PARTUUID="3789b15b-cb17-ee46-8591-859db799cb07" /dev/sdb1: LABEL="NAS" UUID="721887637963356003" UUID_SUB="2763534249674358702" TYPE="zfs_member" PARTLABEL="zfs-9b9bbb93b7b7bbcf" PARTUUID="1a20fbbd-5cf9-cc46-ab02-2084b44f1efe" /dev/sdb9: PARTUUID="8bdc2438-456c-1643-9193-05aeefa16bf8" /dev/sdc1: LABEL="NAS" UUID="721887637963356003" UUID_SUB="12980099901542533778" TYPE="zfs_member" PARTLABEL="zfs-54febf417c774651" PARTUUID="dd69e60f-78a3-8c45-be3d-ab6bbae4bbb0" /dev/sdc9: PARTUUID="6fd75129-0472-ab4f-b83c-91552d466cb7" /dev/sdd1: LABEL="NAS" UUID="721887637963356003" UUID_SUB="10649944750575006148" TYPE="zfs_member" PARTLABEL="zfs-371f350dc5f8b5ee" PARTUUID="8953ac79-2fb6-414c-b159-66cf13bb913c" /dev/sdd9: PARTUUID="a2066746-22b7-fb44-8629-9f2e2c1f75ea" and last: sudo blkid -p /dev/sda /dev/sda: VERSION="5000" LABEL="NAS" UUID="721887637963356003" UUID_SUB="10629598274000407582" TYPE="zfs_member" USAGE="filesystem" PTUUID="478ce577-056b-4de2-bb0e-0d28a37f4223" PTTYPE="gpt"
