During initial setup, I manged to accidentally select the ASG 7.450 iso image as my backup image, rather than the actual backup.
This resulted in a long delay, then a series of "not responding" UI errors, then a popped-under "Corrupt Backup" warning.
Cancelling out, completing configuration, and then using the standard "Import backup" functionality led to a helpful "invalid extension" message that alerted me to my idiocy [:)]
The invalid extension checking should probably be extended to the backup restore on the startup wizard?
