Smart Update just isn't working!

My SuperDuper backup today failed with the following messages:
| 08:23:36 AM | Info | error (22) from /Volumes/Boot-300GB. (Invalid argument)
| 08:23:36 AM | Error | ****FAILED****: result=5632 errno=22 (Unknown error: 0)

And in the console:

I don't know if it is relevant but I recently applied the most recent Leopard security update, and I also am using a partition in a new 1TB drive. SuperDuper version is 2.5
