Do you think it's possible for you to reproduce this? If you have the original pre-dbox mail and you convert it to a new and empty dbox+sis and reading it gives this error message, I'd really like to get the original mail.

Highly unlikely. There have been other similar error reports, so I know there's a bug somewhere. I just don't really know where. I haven't managed to reproduce any SIS errors with any of my tests.
