gdb backtrace with debug symbols

When the second monitor resumes from standby the greeter shows the "have to unlock session using loginctl ..." and shortly after that the screen goes black with only the mouse pointer still movable.

STEPS TO REPRODUCE
1. Wait for auto screen lock and till all monitors enter standby
2. move mouse
3. crash

kwin_wayland only

Started kwin_wayland from tty and waited for the greeter to appear. Disconnected the second monitor and collected the backtrace.
