Summary: System Settings crashes in FirewallClient::capabilities() after going to the "Firewall" item
Product: [Applications] systemsettings Reporter: Никита <nikinario>
Component: kcm_firewallAssignee: Plasma Bugs List <plasma-bugs-null>
Status: RESOLVED DUPLICATE    
Severity: crash CC: nate, tcanabrava
Priority: NOR Keywords: drkonqi
Version First Reported In: 5.21.0   
Target Milestone: ---   
Platform: Neon   
OS: Linux

Sentry Crash Report:

Description Никита 2021-02-16 17:31:25 UTC 
Application: systemsettings5 (5.21.0)

Qt Version: 5.15.2
Frameworks Version: 5.79.0
Operating System: Linux 5.4.0-65-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.0
Distribution: KDE neon User Edition 5.21

-- Information about the crash:
- What I was doing when the application crashed:  If I go from it to any other item, the window blinks (as if it slows down) and if you then open the "Firemaer" item again, then "System Settings" crashes.

- Custom settings of the application: After installing "Dr Web" and updating the "Kde Neon", the "Firewall" item appeared in the "System Settings".

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Параметры системы (systemsettings5), signal: Segmentation fault
