SUMMARY
After some time, plasmashell starts crashing.  When it starts, it just keeps getting worse, until every mouse click or mouse over triggers a crash.  In this case, got a notification at a time I was too busy to read; then clicked notifications icon in systray --> instant crash.  

STEPS TO REPRODUCE
1. use the system -- 3 screens, panels on each screen. Only main screen has full panel.
2. mouse over|click any panel
3. 

OBSERVED RESULT
crash & auto-restart (though not always -- need to issue plasmashell --replace)
