Since version 2.1.19 (released 2017-03-02) GnuPG uses a builtin fallback if no key server is configured. Since then the fallback used by Kleopatra is obsolete.

|rKLEOPATRAf2d388ea2073 Show an error if the usage of key servers has been disabled
The fallback wasn't used/offered for any GnuPG versions after 2.1.19.
To check that the fallback isn't used with GnuPG versions supporting the special value "none" to disable the usage of an OpenPGP key server do the following:
- Set "none" as key server.
- Try to export an OpenPGP key to a key server or to refresh the OpenPGP keys.
Expected result: You'll get an error message explaining why the operation isn't possible.
