openSUSE Leap 42.3 (x86_64) KDE 5.32.0 Plasma 5.8.7 Qt version 5.6.2 Kater 17.04.2 If you try to open an already open session, kate prompts you to re-use the already open session. This is good, but if you say 'Yes' then it fails to close the unused instance of itself. Kate should close itself because you agreed to just switch to the already running session. See also bug 277089 from 2011 (7 years!?!?) as a better solution.
