Bug 489612

Application: baloo_file_extractor (6.3.0)

Qt Version: 6.7.1
Frameworks Version: 6.3.0
Operating System: Linux 6.9.6-200.fc40.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 40.20240702.0 (Kinoite)"
DrKonqi: 6.1.1 [CoredumpBackend]

-- Information about the crash:
File Indexing on System Settings was disabled due to previous crashes, but the file extractor is still running. No other information was provided by logs, except for the audit.log spitting out a number of these errors:

./audit/audit.log:type=ANOM_ABEND msg=audit(1719817861.788:228): auid=1000 uid=1000 gid=1000 ses=3 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 pid=5227 comm="baloo_file_extr" exe="/usr/libexec/kf6/baloo_file_extractor" sig=11 res=1AUID="$USER" UID="$USER" GID="$USER"

The crash can be reproduced every time.
