Clone with Everything, Linked Clone errors

[Socratis]

• Select a VM ("Test") and choose "Clone". The VM did not have snapshots, but it doesn't really matter.
• Switch to "Expert Mode", if not already selected.
• The defaults are: Full Clone (for CloneType), Current machine state (for Snapshots).
• Select in that order: Everything (for Snapshots), Linked Clone (for CloneType). Press "Clone":

  Failed to clone the virtual machine Test.
  
  Linked clone can only be created for a single machine state.
  
  Result Code: NS_ERROR_INVALID_ARG (0x80070057)
  Component: SnapshotMachine
  Interface: IMachine {b2547866-a0a1-4391-8b86-6952d82efaa0}
  

• We return to the Clone dialog. If you Cancel out, you see the results:
  • No "Test Clone" VM has been created.
  • A snapshot for the "Test" VM has been created: "Linked Base for Test and Test Clone".

Just had this happen with:

Version: Version 5.2.12 r122591 (Qt5.6.2)

Host type: Windows 10 Pro x64 Version 1803 17134.112

Guest type: linux

Failed to clone the virtual machine vm.

Linked clone can only be created for a single machine state.

Result Code: E_INVALIDARG (0x80070057) Component: SnapshotMachine Interface: IMachine {85cd948e-a71f-4289-281e-0ca7ad48cd89}

This occurs with Oracle VM Virtualbox Manager > highlight a vm > click Clone > Expert Mode > first under "Snapshots" click radio button "Everything" > next under "Clone type" click "Linked Clone" (notice how radio buttons under "Snapshots" are greyed out) > click button "Clone"

WORKAROUND: If under "Snapshots" click radio button "Current machine state" before clicking under "Clone type" clicking radio button "Linked Clone" then this consistently doesn't happen for me, and I have a Linked Clone as expected.

Hey, I had forgotten about that one... ;)

The idea of the ticket is that the GUI should force-revert to "Current machine state" if "Linked Clone" is selected. And to avoid creating the snapshot!
