Bug 394662

Application: baloo_file (5.32.0)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.126-48-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
- What I was doing when the application crashed:
I was doing nothing. Baloo crashes every time, a few seconds after I logged into Plasma. The crash is systematic on this computer.

The crash can be reproduced every time.

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