-- Information about the crash:
Prior to the crash, I attempted to upload a file to the web using the file
picker brought up by my browser. This took almost two full minutes to do, and
during the process I noticed at least one failure notification from "Portal",
where it was "Examining" the linked KDE Connect devices, and failed in my
camera roll. I then opened Dolphin myself and noticed a slow start time,
followed by a ~15 second pause when accessing any local directory on the
machine. Upon clicking a linked KDE Connect device in the left Devices panel,
the application became unresponsive trying to load the kdeconnect:// path, and
eventually crashed. The sluggish behaviour and unresponsive-followed-by-crash
behaviour has recurred with each subsequent opening of the program. Attempting
to open the file picker via my browser also triggers the same "Examining"
notification followed by a failure on the same KDE Connect device. I have not
yet attempted a restart as I awaited the debug information download.

The crash can be reproduced every time.
