Application: baloo_file (5.47.0)
 (Compiled from sources)
Qt Version: 5.11.0
Frameworks Version: 5.47.0
Operating System: Linux 4.17.0-gentoo x86_64
Distribution: "Gentoo Base System release 2.6"

-- Information about the crash:
- What I was doing when the application crashed:
Watching a local video file, rsyncing remote server backup to the same RAID 1 LUKS encrypted EXT4 volume where the file was played from - rsync was writing two big DB gzipped backup files during the crash. Found KDE crash reporter icon after rsync finished.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
