I agree it's not exactly a bug. But the fact remains that differentials are running based on a non-existent full backup (a backup that's part of a volume snapshot). It could've been avoided if the VSS writer recorded it as 'copy only'.
Agreed, the problem there is that many of the tools that use the VSS writer to back up a SQL database don't have an option for the user to set copy only, and it is not (and cannot be) the default.
