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

[Truong Anh. Tuan]

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.
