Comment 1 Nicolas Fella 2020-10-14 19:24:50 UTC

It would help a lot if you could install kdeconnect-dbgsym and get a new backtrace, otherwise it's hard to tell where it's crashing exactly

Comment 2 voncloft 2020-10-17 23:48:56 UTC

Do you have source code that you can compile this package from?

New crash information added by DrKonqi

kdeconnectd (1.4.0) using Qt 5.15.2

- What I was doing when the application crashed:

Spent several minutes crafting a 3 sentence reply and on clicking send the daemon crashed. I use signal as my default sms application.

Thank you for the bug report! Another bug report that seems to cover the same crash has a more informative stack trace, so I'm marking this 
as a duplicate of that one.
