Public bug reported: gnome-disks works when restoring from a 300 MB image compressed with xz. But it fails when trying to 'restore' from a 12 GB image compressed with xz. This extraction works with mkusb, which uses dd under the hood. The process is described at
https://help.ubuntu.com/community/Installation/UEFI-and-BIOS and the file to 'restore' is http://phillw.net/isos/linux-tools/uefi-n-bios/dd_Ubuntu_16.04-gamma- UEFI-n-BIOS-4-pendrive-12GB.img.xz gnome-disks 'thinks' that the file size is 3.5 GB, so it truncates it, and the result is a corrupted system on the target drive. See the attached screenshot.
