-- Information about the crash:
This happens very frquently, if not always.
I have my laptop running on the nvidia chipset (optimus manager applet) to be
able to connect an external monitor.
I quit work by unplugging the external display then closingthe lid to put the
laptop to sleep.
At home I open the lid, and the first actions triggers a crash. In this case, i
clicked on a window to focus it.
I just clicked on the systray applet expander to get the name of the optimus
applet I was using , and then plasma crashed as well.
The crash can be reproduced every time.
