Kdeconnectd crashes all the time

Tue Dec 22 19:34:02 GMT 2020

For some time now (I cannot pinpoint it exactly), the kdeconnectd always
crashes when the system runs more than about 2 hours. The
kdeconnectd-error shows this in "developer information":

Application: kdeconnectd (kdeconnectd), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Is this in any way helpful? I'm using Debian 10 on a Lenovo T440 laptop.
