Hell Mulas, I tried to get to the source line of you dmesg output:
[254868.778098] tracker-miner-f[1916712]: segfault at 8 ip 00007f9bf641bc18 sp 00007fff0ca38e10 error 4 in libtracker-sparql-3.0.so.0.402.0[7f9bf63f9000+6a000] likely on CPU 2 (core 2, socket 0) [254868.778109] Code: 18 64 48 2b 04 25 28 00 00 00 75 35 48 83 c4 20 5b c3 48 8b 44 24 10 48 8d 15 84 dd 04 00 be 08 00 00 00 48 8d 3d fd 77 04 00 <48> 8b 48 08 31 c0 e8 5d de fd ff 48 8b 7c 24 10 e8 03 da fd ff eb
I think this relates to this source line: https://sources.debian.org/src/tracker/3.4.2-3/src/libtracker-sparql/core/tracker-data-manager.c/#L4050 g_critical ("Could not set up interface : %s", error->message); But a full backtrace is probably still needed by the maintainer. You could probably collect one by installing systemd-coredump. Then journalctl should contain a more detailed information on which functions are involved. Kind regards, Bernhard
