New crash information added by DrKonqi

plasmashell (5.10.5) using Qt 5.9.1

- What I was doing when the application crashed:
it is probably linked to something changing automatically in the plasma bar, since it crashed without my presence.

- Unusual behavior I noticed:
This is what I also see in .xsession_error
*** Error in `/usr/bin/plasmashell': double free or corruption (fasttop): 0x00007fa950019400 ***
