VBoxManage.exe crashes when unregistering a VM with no storage

[Justin R. Cutler]

It appears that attempting to unregister and delete a VM with no attached storage causes VBoxManage.exe to crash.

Steps to reproduce:

1. Create and register an "empty" VM

   C:\Program Files\Oracle\VirtualBox>VBoxManage.exe createvm --name Test --register
   Virtual machine 'Test' is created and registered.
   UUID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
   Settings file: 'C:\Users\<username>\VirtualBox VMs\Test\Test.vbox'
   

2. Attempt to unregister and delete the VM

   C:\Program Files\Oracle\VirtualBox>VBoxManage.exe unregistervm Test --delete
   VBoxManage.exe: error: Code RPC_E_SERVERFAULT (0x80010105) - The server threw an
    exception (extended info not available)
   Context: "Delete(ComSafeArrayAsInParam(aMedia), pProgress.asOutParam())" at line
    167 of file VBoxManageMisc.cpp
   

At this point, a crash dialog will pop up with the following text (Windows 7 x64 host):

VBoxManage.exe has stopped working

A problem caused the program to stop working
correctly. Please close the program.

 -> Close the program

vboxmanage unregistervm xxx --delete always crashes for me, even if storage is attached. To reproduce, create a new VM with the Oracle VM VirtualBox Manager, accepting all defaults. This creates a new VM with a harddisk. Now delete the VM with vboxmanage and you will receive the same error as noted above.

My Host type is w2k8@64.

Confirmed. Windows 64-bit host problem.
