Bug 366296

Application: baloo_file (5.23.0)

Qt Version: 5.6.1
Frameworks Version: 5.23.0
Operating System: Linux 4.6.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:

Just start KDE. I always get this crash. Since a few months.

No matter if the DB is inconsistent or whatever... there should be no crash, just an informative message that tells me what is wrong and how I can (manually) solve it.

Regards, Tim

The crash can be reproduced every time.

-- Backtrace:
Application: Baloo File Indexing Daemon (baloo_file), signal: Segmentation fault
