seamless mode fails while starting a snapshot — at Initial Version

Description
When (re)starting a snapshot that was taken while in seamless mode, the seamless mode does not work from time to time (but the default window-mode is entered). This also happens when we explicitly start in seamless mode doing both:
- VBoxManage setextradata "GUI/Seamless" on, as well as
- VirtualBox --startvm <name> --seamless
One way to (quite) deterministically reproduce this error is on a Windows XP host, to shut down Windows while VirtualBox is still running in seamless mode and rebooting Windows and starting the VM again.
But this problem is not only limited to Windows XP hosts, it also appears within Windows 7 and Linux hosts. However, it is unclear when exactly it happens. Is there any workaround to *really* force the machine to startup in seamless mode? Are there any files which remain in an unclean state when VirtualBox is killed, instead of powered down via the API?
