[Git Master] Crash when clicking the back button on the Display view
A pretty nasty one. Boxes 3.31.90-478fc136 will crash when clicking the back button on the Display view. This is consistently reproducible, with multiple VMs. When it crashes, Boxes will leave qemu processes behind still taking up resources, and will not be able to connect to the virtualization backend until these processes are killed.
