plasmashell (5.12.9) using Qt 5.9.5

- What I was doing when the application crashed:
I had just finishing copying files to a USB stick, and I had safely
removed the stick without any problem.
Before than that, I had been working with LibreOffice Writer.

- Unusual behavior I noticed:
When I told the sistem to shutdown, Everything went black for some second, the
gradually the screen reappeared (first the background image, then the task bar,
then the desktop Icons
