  What exactly happens depends on how Konsole is started.
  If it's started via plasmashell (e.g. menu), the process tree is:
  
    kdeinit5: Running...
     \_ /usr/lib64/libexec/kf5/klauncher --fd=9
     \_ kded5 [kdeinit5]
     \_ /usr/bin/ksmserver
     |   \_ /usr/bin/kwin_x11 -session 10cf9da065000150283451700000087800055_1510626492_975085
     |   \_ /usr/bin/plasmashell
     |   |   \_ /usr/bin/konsole
     |   |       \_ /bin/zsh
     |   |           \_ ps faux
  
  If you register a custom shortcut to start a terminal and launch Konsole via that, you end up with:
  
    kdeinit5: Running...
     \_ /usr/lib64/libexec/kf5/klauncher --fd=9
     \_ kded5 [kdeinit5]
     |   \_ /usr/bin/konsole
     |       \_ /bin/zsh
     |           \_ ps faux
     \_ /usr/bin/ksmserver
  
  So it's either forked from plasmashell or kded on my system at least.
  
  The issue has also been observed before: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=860269
  but sadly the fix got lost in the Debian bugtracker.
