-- Information about the crash:
The Plasma-Shell didn't works anymore as usual. More than one crash per day each time a select another virtual desktop or switch between open applications no matter if native plasma application or not, e.g. switch between `firefox` & `kate`.

The crash can be reproduced every time.
