rafaelff [1] filed a deletion request for putty-freedesktop [2]:

The putty-freedesktop package was created only to provide a .desktop file to be used with 'putty' package from official repositories. However, as of putty 0.70-2, those files were already included. Therefore, currently this package contents conflict with 'putty' and it isn't needed anymore. Please remove.
