kipi-plugins-common packages .desktop files without corresponding executable files

The kipi-plugins-common includes .desktop files, without including the corresponding executable files. The corresponding executable files are found in kipi-plugins. kipi-plugins-common does not depend on kipi-plugins, which means useless .desktop files can be installed by the user.

Steps to reproduce:

$ sudo apt-get install kipi-plugins-common
# ...
$ grep '^Exec' /usr/share/applications/kde4/photolayoutseditor.desktop
Exec=photolayoutseditor
$ photolayoutseditor
The program 'photolayoutseditor' is currently not installed. You can install it by typing:
sudo apt-get install kipi-plugins
$ sudo apt-get install --no-install-recommends kipi-plugins
# ...
$ photolayoutseditor
# works

kipi-plugins should include both the executables and the .desktop files, and kipi-plugins-common should include neither.

An important sympton of this bug is in the Ubuntu Software Centre. If you search for "Photo Layouts Editor" in the Ubuntu Software Centre and install it, you will get a non-functioning icon in the launcher.

I don't know if fixing kipi-plugins-common and kipi-plugins will automatically fix the catalogue in the Ubuntu Software Centre, so I'm marking the Software Centre as affected.
