New crash information added by DrKonqi

plasmashell (5.6.2) using Qt 5.5.1

It appears that the lock screen issue has been fixed with 5.6.2 but the missing
panel issue remains.

- What I was doing when the application crashed:
I unlocked my session after leaving it idle. The computer had not suspended;
only the display had gone to sleep

- Unusual behavior I noticed:
The lock screen unlocked and everything appeared to work (including Alt+Tab and
Ctrl+Space) but the panels were missing.
