crash log for kde6 after QR code scan

DESCRIPTION
kded6 crashes when attempting to scan/import a Wi-Fi connection using a QR code
from the Plasma NetworkManager applet.

STEPS TO REPRODUCE
1. Open the Plasma NetworkManager applet from the system tray.
2. Open the Wi-Fi section.
3. Select the option to scan/import a Wi-Fi QR code.
4. Provide a valid Wi-Fi QR code that wasn't scanned/saved previously.
5. Wifi successfully connects to the provided network.
6. Observe that kded6 crashes at the same time as step 5.

OBSERVED RESULT
kded6 crashes while processing the QR code.

EXPECTED RESULT
kded6 should continue running normally.

ADDITIONAL INFORMATION
kde6 has been updated with the Plasma Frameworks version 6.28.0 on Fedora KDE

The timestamps are wrong in my crash report probably because I was travelling
between different time zones.
