Bug 395666

Application: yakuake (3.0.5)

Qt Version: 5.11.0
Frameworks Version: 5.47.0
Operating System: Linux 4.14.49-1-lts x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I have a dell laptop which supports up to 10 touches. I am using kwin_wayland and and tried touching with several (maybe 8) fingers when yakuake is in full screen.

- Unusual behavior I noticed:
yakuake crashed

- Custom settings of the application:
kwin_wayland, yakuake in fullscreen

The crash can be reproduced every time.

-- Backtrace:
Application: Yakuake (yakuake), signal: Segmentation fault
