Microsoft Virtual Machine Converter 3.0 multiple disks bug

When converting a Windows 2008 R2 VM that contains multiple disks (VMDKs), the converting process with Microsoft Virtual Machine Converter (MVMC) 3.0 fails with the following error:

Microsoft Virtual Machine Converter encountered an error while attempting to convert the virtual machine. Log 

Details: A task may only be disposed if it is in a completion state (RanToCompletion, Faulted or Canceled).

This is a bug that was already available in MVMC version 2.0 and fixed in MVMC 2.1.  MVMC 2.1 is hard to find so here is a link to my OneDrive.
