[Fedora-packaging] Error with desktop-file-install

Hi there, I am packaging the new package: pencil [1]. Finally, necessary changes (folder, package released, etc.) have been made in upstream. I also updated .spec file and retried to build the package. However, I got his error message (It seems to relate to the new entry desktop-file-install): Checking for unpackaged file(s): /usr/lib/rpm/check-files /home/tuanta/rpmbuild/BUILDROOT/pencil-2.0-2.fc17.x86_64 error: Installed (but unpackaged) file(s) found: /usr/share/applications/pencil.desktop RPM build errors: Installed (but unpackaged) file(s) found: /usr/share/applications/pencil.desktop Any helps are highly appreciated.
