- What I was doing when the application crashed:
I sent two pdf files to my phone via KDEConnect. This appears to have caused kdeinit5 to crash multiple times in quick succession. This happens every time.
The connection is via 5GHz wifi.

This is the information provided for KDEinit5 crash:
Executable: kdeinit5 PID: 17802 Signal: Segmentation fault (11) Time: 27/04/2021 14:16:48 BST

The crash can be reproduced every time.
