I tried in the same session to restart plasmashell from konsole, but it always crashed.
Comment 2 Martin Klapetek 2015-06-03 10:29:11 UTC 
Thanks for the report

Have you tried any other applets? Do they all crash or just the CPU monitor one?
Comment 3 computer-driver 2015-06-03 18:11:07 UTC 
Yes, I have. Before CPU monitor I added succesfully a widget with a smile as icon (I don't remember its name).
