Ingo suggested that the Kleopatragroupsrc would be better placed into the GNUPGHOME, as it relates to certificates, not Kleopatra. When setting up a separate GNUPGHOME for testing, those group definitions should be taken from there, as are the certificates.
When we move it, we should rename it, too. How about kleopatragroups.conf?
