-- Information about the crash:
I entered plasma systemmonitor, visited the processes tab and sorted backwards by memory
strangely it appears many processes consume "-1 KiB" ram, and the data for many processes is not filled in
sometimes it occurs immediately, sometimes after a few seconds and after clicking on processes, sometimes not at all (but it does hang for quite a while after interacting with the ui)  
the app crashes with a Segmentation fault

The crash can be reproduced sometimes.
