6.0.10 snaphot fails on NFS share with savestate

Description
This all works with 5.2.X. A fresh install of 6.0.10 yields the following bug:
With a VM located on an NFS share, if that VM is put into "savestate", and we try to clone that VM, the clone fails with the following error:
Progress state: VBOX_E_IPRT_ERROR VBoxManage: error: Clone VM failed VBoxManage: error: Code VBOX_E_IPRT_ERROR (0x80BB0005) - Runtime subsystem error (extended info not available) VBoxManage: error: Context: "RTEXITCODE handleCloneVM(HandlerArg*)" at line 609 of file VBoxManageMisc.cpp
If the VM was shutdown using poweroff or acpipowerbutton, the clone works as expected.
Note: If the VM is located on a local ext4 filesystem, cloning of a savestate VM works as expected. The issue only happens if the VM is on an NFS share AND the vm was put into "savestate".

Removing 6.0.10 and installing 5.2.X, everything works as expected.
