Restore Disk Image stuck at 0% using 100% of CPU, then Disks crashed when I closed its window

[Alexander Browne]

I was attempting to use "Restore Disk Image" to write an Ubuntu MATE iso to flash drive. The task stalled at 0%, and htop showed Disks using 100% CPU. I cancelled the task and clicked the window close button, and then Disks crashed.

Status changed to 'Confirmed' because the bug affects multiple users.

[Alexander Browne (elcste)]

This occurs for me on a system that had been upgraded from 17.04 to 17.10. I've now upgraded it to 18.04 pre-release and Disks's restore function is working again. It does seem to use a lot of CPU, however, but I haven't compare it with another system very scientifically.
