Application: systemsettings5 (5.19.5)

Qt Version: 5.15.0
Frameworks Version: 5.74.0
Operating System: FreeBSD 12.2-RELEASE amd64
Windowing system: X11
Distribution (Platform): FreeBSD Ports

-- Information about the crash:
- What I was doing when the application crashed:

clicked on "Get New Global Themes ..."  and hovered over 

1. .. "Ambient-Blue-Global" theme and hit the Install button that only appears after hovering ... twiddled thumbs for a while (for a theme install, this took oddly way too long! A 600MB ISO takes less time!!) and nothin'. It did seem to install content for "Plasma Style", but gave no indication that an entire new global theme was installed: icon in Global Themes is missing. The app died without crash notice --or maybe I just didn't notice.

Reopened the same app and chose to install a different global theme:
2. "Neonyt-Solid-Global" - at this point there was less network activity, no icons installed and a final crash of the System Settings app.


- Unusual behavior I noticed:

Since I have the "Network speed" widget in the bottom panel, I could see that the first theme attempted some downloads which maxed out the ingress bandwidth to circa 93%. (ISP bandwidth approx 400Mbps). 

PS: While the bugtracker correctly picked the OS distribution method it failed to realize that KDE for me is a 'package' (binary), not a 'port' (source). Also the bug report stated somewhere FreeBSD 12.1 - this is also incorrect:

# uname -a
FreeBSD {localhost} 12.2-RELEASE FreeBSD 12.2-RELEASE r366954 GENERIC  amd64

The crash can be reproduced every time.
