Bug 399006

Application: yakuake (3.0.5+)

Qt Version: 5.11.1
Frameworks Version: 5.51.0
Operating System: Linux 4.15.0-34-generic x86_64
Distribution: KDE neon Developer Edition

-- Information about the crash:
I changed Yakuake settings then tried to split the yakuake screen ctrl+shift+( but it crashed, I tried again without changing setting and no crash, then changed settings and only closed the tab and got another crash.
It might be related to shortcuts.

The crash can be reproduced every time.

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