systemsettings5 (5.21.0) using Qt 5.15.2

- What I was doing when the application crashed:

1. Opened systemsettings.
2. Opened firewall page.
3. Open another page like "About system".
4. Opened firewall page again.
5. Boom

still happening for me with Plasma 5.21.1

not sure if the fix in master made it in the minor version

maybe change the status to "open" to avoid getting duplicate bug reports. The bug is clearly not fixed yet.
Comment 16 David Edmundson 2021-03-16 23:40:25 UTC 
It is, it just isn't backported for whatever reason
Comment 17 Nate Graham 2021-03-17 15:55:14 UTC 
The commit has now been backported.
Comment 18 Nate Graham 2021-03-19 14:45:41 UTC 
With current git master, I am still getting the firewall KCM crashing when opened a second time, but the backtrace is now different. I'll file it separately as Bug 434623.
