SUMMARY
System Monitor crashes when you go to the Processes tab, enter a search in Tree View, and then click on some of the displayed processes. Occasionally it is not reproducible, but it is pretty easy to trigger usually.

STEPS TO REPRODUCE
1. Launch System Monitor and go to the Processes tab
2. Enter a search. I used "kwin"
3. Switch to Tree view
4. Click on any of the processes in the tree.

OBSERVED RESULT
System monitor crashes after clicking on a process in the tree

EXPECTED RESULT
System monitor should not crash
