The manual for BBDB is currently a stub, and thus bbdb.info is not installed by Fedora (cf. bug #1192873), but bbdb.pdf (with the same content) is generated and installed. It should be removed as well. (Probably applies to Fedora 24, too.)
I'm not sure I bother with the F24 package, as it will soon be EOL and the useless manual doesn't hurt too much. But I'll fix newer versions.
