Error recording from CLI: "The machine is not mutable, saved or running" => fixed in SVN/next maintenance

VirtualBox Version 6.0.8

VM is running in headless mode. I would like to start to record the display from command line. Earlier it was possible by executing this command:

VBoxManage controlvm <vm_name> videocap on

And when I wanted to stop the recording the following command was executed:

VBoxManage controlvm <vm_name> videocap off

If I know it well from VBox 6.0(?) this is the valid command for my purpose:

VBoxManage controlvm <vm_name> recording on

But now I got these error messages:

VBoxManage.exe: error: The machine is not mutable, saved or running (state is Running)
VBoxManage.exe: error: Details: code VBOX_E_INVALID_VM_STATE (0x80bb0002), component MachineWrap, interface IMachine, callee IUnknown
VBoxManage.exe: error: Context: "COMSETTER(Enabled)(TRUE)" at line 1879 of file VBoxManageControlVM.cpp

When the GUI of the VBox is used for starting/stopping records (Settings\Display\Recording\Enable Recording) the process is done well but executing from Command Prompt is getting me stuck...

Fixed in 6.0.9r131597 and later. Just pick up the latest test build from the Testbuilds page.

Confirmed as fixed with 6.0.9 r131597 and 6.0.97 r131601.

I have other issues with the recording, but that's a story for another ticket...
