Description Michael Brach 2016-12-16 16:43:49 UTC 
Application: kontact (5.1.3)

Qt Version: 5.5.1
Frameworks Version: 5.23.0
Operating System: Linux 4.4.0-53-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
1. new email edit window is open
2. klick on select email adress icon, in order to show addressbook list.
3. Kontact crashes while or after selecting an email address from the addressbook

- Unusual behavior I noticed:
heavy CPU load due to baloo re-indexing

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
