commit 13950a98522818b27b3048617acb0282b65b54b3
Author: Andre Heinecke <aheinecke at intevation.de>
Date:   Mon Nov 20 11:54:08 2017 +0100

    Launch Kleo/GPA in the background on start
    
    * src/engine-assuan.c (spawn_background): New.
    (op_assuan_init): Create background thread to launch kleo.
    
    --
    This does not slowdown the startup as it happens in a different
    thread but is intended to speed up the opening of the key
    resolution dialog when kleopatra is not running and help to
    avoid startup problems mentioned in T3401
    
    GnuPG-Bug-Id: T3401
