Bug 457062

Application: plasmashell (5.24.4)

Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.14.21-150400.24.11-default x86_64
Windowing System: X11
Distribution: "openSUSE Leap 15.4"
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Somtimes on logging in to plasma, the NetworkManagers does not start, or is slow in getting an address from WiFi. In such cases, the comic strip widget is empty.

Then, after re-estabelishing network connection in the comic strip widget I choose "Jump to strip". That causes a crash of KDE every time.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
