Snapshot restore corrupts VM disk config

Description

When I restored a snapshot using the GUI it gave an error but didn't give an error message. It made the VM inaccessible. When I restarted the GUI the error message became visible: VBOX_E_OBJECT_NOT_FOUND. It turns out that it had broken the UUIDs of the disks. I had to remove them from the config file using a text editor then add them back using the GUI. This looks like bug numbers 8595 or 8648 or 8363 but they are all closed yet the problem remains.

Without a testcase it's hard to debug. This crash could be specific to your VM config or to your environment. The error message you saw might be the result of a VBoxSVC crash. A core dump and a reproduction scenario could help to debug this problem.

I can't risk trying to use snapshots ever again on our live system now. I might be able to try with a new VM but don't know how I would obtain sufficiently detailed debugging information (especially since I can't find a core). Maybe someone with more in-depth knowledge of vbox internals and how to debug it could try to reproduce the problem. Especially since it's been reported several times by other people, the person who investigated and tried to fix it back then must have a better idea than me of how to track and solve the problem. Thank you.
