Bug 401688

Application: baloo_file_extractor (5.52.0)

Qt Version: 5.11.2
Frameworks Version: 5.52.0
Operating System: Linux 4.15.0-39-generic x86_64
Distribution: KDE neon User Edition 5.14

-- Information about the crash:
- What I was doing when the application crashed:
I had shut down my computer while baloo was consuming a lot of system resources indexing things. This crash happened during the next boot sequence.

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Extractor (baloo_file_extractor), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
