EXPECTED RESULT

Raspberry 2B stretch with kernel  4.14.71-v7+

KDE Plasma Version: 5.8.6
KDE Frameworks Version: 5.28.0

ADDITIONAL INFORMATION
neither gdb nor valgrind return useful information

akonadiconsole works, just crashes on hitting the tab 'browser'
superfast mmc
no errors in any other logfile

libreoffice working flawlessly
power with ABB 30W 5V stabilized switching supply

Xsession is no longer attaching information (no errors) to .xsession-errors  (I have set it to overwrite instead), so there is no problem with full drives anymore. 
cpu-temperature normally about 45 deg celsius, never exceeding 55 deg
After three crashes the GUI restarts but recovers in about 60 seconds
memory split 128
swap uses about 40% 
used space on root partition 33% of 15 G
enough space available
Chromium Browser works fine and can take 10 ore more pages
I am willing to help, but I am at the end of my skills now.

ALL CLEAR
Happy to report that:
After reinstall on a fresh updated and upgraded copy of raspbian stretch lite and a very careful step by step setup of kmail, korganizer and further components kontact is working flawlessly now.
Not clear what caused the problems. As usual I have set up the basics and checked all logs for errors.
Based on the experiences I made with the first trial I have made a few modifications since after reinstalling the system was hanging after 5 minutes.
1. Commented out all entries in /etc/dphys-swapfile. Obviously KDE is controlling this 
2. created a cron run script to keep ~/.xsession-errors size below 200000
This feature is causing big problems on a raspberry with limited resources! I saw that I am not the only one who is complaining.
