Application: baloo_file_extractor (5.29.0)

Qt Version: 5.6.2
Frameworks Version: 5.29.0
Operating System: Linux 4.8.15-200.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

-- Information about the crash:
- What I was doing when the application crashed: booting up the system without doing anything else. The failure report window allows to restart the application, which appears to work. So, it is a startup issue.

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Extractor (baloo_file_extractor), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
