perl-Panotools-Script package delivers some graphical application with desktop files that refer "hugin" icon. But perl-Panotools-Script does not deliver the icon file. Instead it expects it will be provided by hugin-base package. But hugin-base package does not deliver the icon. It's delivered by "hugin" package. (See bug #1120577 for more details.) Would it possible to move /usr/share/pixmaps/hugin.png to a separate package, let's say "hugin-icon"? Then both hugin and perl-Panotools-Script would run-require hugin-icon.
