  Target Milestone: ---

Application: konsole (16.04.3)

Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.13.0-45-generic x86_64
Distribution: Linux Mint 18.3 Sylvia

-- Information about the crash:
- What I was doing when the application crashed:
Close the windows; clean scroll and reset, then close.
- Unusual behavior I noticed:
After crash Konsole almost always stays at 10/12% CPU usage.

The crash can be reproduced almost always.

-- Backtrace:
