All fine. Just VBoxBFE wasn't updated lately to take the disk image 
handling changes into account. It was just silently broken without 
anyone noticing, as VBoxBFE isn't packaged. Thanks for spotting this.

VBoxHDD is the old VDI only driver, which was removed with version 2.1. 
Should be fixed now in latest trunk version.
