Without splitting off a -devel package or deleting the .pc file, it's
not possible to fix this.

Package nautilus contains a pkgconfig template file, which lists other
pkgconfig files as requirements. When these files are included in
other RPM packages, the RPM package "Requires" must be complete. Else
pkgconfig fails, prints an error message and returns an error code for
standard queries like "pkg-config --exists foo-1.0", "pkg-config
--cflags foo-1.0" or "pkg-config --list-all".
