Qt Version: 5.6.0
Operating System: Linux 4.4.7-300.fc23.i686+PAE i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Logging in. Baloo crashing was the first thing that happened.

- Custom settings of the application:
FreeIPA is used.
/home is on NFSv4
Tried both sddm and lightdm-gtk

The crash can be reproduced every time.

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