xfce-terminal zombie process

Why do I have a zombie process upon opening a xfce-terminal, always:


$ps -el
0 R  1000  3979  2370  0  80   0 - 195137 -     ?        00:00:00 xfce4-terminal
1 Z  1000  3985  3979  0  80   0 -     0 -      ?        00:00:00 xfce4-terminal <defunct>

or 

$ps lx
0  1000  3979  2370  20   0 781060 55424 -      Rl   ?          0:00 xfce4-terminal
1  1000  3985  3979  20   0      0     0 -      Z    ?          0:00 [xfce4-terminal] <defunct>

Some imported SUSE bug/issue?
Because I don’t have it at openSuse 13.2 & Tumbleweed but experience it at Leap 42.2 only in both cases - upgrades from 13.2 and fresh new installs.
Irritating.

Perhaps an XFCE bug (as distinct from a SUSE bug).

Honestly, this is nothing to be concerned about. The zombie process is using very little.

Whenever a process ends, a zombie process is left behind. It is mostly a place holder with a small amount of information about the process that ends. The originating process is supposed to occasionally check for that. And when it does, the zombie goes away.
