Running bedup as root, then as a normal user results in a unhelpful error message

[leijurv]

The sqlite database can't be read, because it was created as root, and my normal user doesn't have permission to read it.

The resulting error simply says it was unable to read the database file, so I thought it might be corrupted or missing, but actually it just didn't have permission.
