New crash information added by DrKonqi

kdeconnectd (21.04.1) using Qt 5.15.2

- What I was doing when the application crashed:

I was transferring 3 files from my laptop and the transfer seemed to be blocking so I canceled the transfer via the notification on the receiving computer and it obviously caused the daemon to crash.

Marking this confirmed, as one of the duplicates with a worse trace was as well. Given that there seem to be no matching traces in quite a while, it can probably be considered resolved.
