Why should we care about that situation if we *do* provide a database?
Distributions can decide to exclude some files from their packages, but
it's their problem, not ours.

Yes, but a comprehensible error message is useful even if somebody messed up the system/configuration.

Yes, but a comprehensible error message is useful even if somebody messed up the system/configuration.
