Application: plasmashell (5.16.4)

Qt Version: 5.12.3
Frameworks Version: 5.60.0
Operating System: Linux 5.0.0-23-generic x86_64
Distribution: Feren OS Next

-- Information about the crash:
- What I was doing when the application crashed:
Applying a Look & Feel with a customised panel layout on it - custom panel layouts being added as panels also triggers this crash.

- Custom settings of the application:
The panel consists of these applets:
org.kde.plasma.uswitcher (unofficial)
org.communia.apptitle (unofficial)
org.kde.plasma.appmenu (official)
org.kde.plasma.panelspacer (official)
org.kde.plasma.kimpanel (official, if required - just like Vanilla Plasma panel configurations this is only added if it's needed)
org.kde.plasma.systemtray (official)
org.kde.plasma.eventcalendar (official)
org.kde.milou (official)
org.kde.plasma.notifications (official)

The crash can be reproduced every time.

-- Backtrace:
