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

Unfortunately none of these backtraces is complete, if someone still sees this crash, could you install the debuginfo packages (name differs depending on distro) and post the backtrace again?
