Sentry Crash Report:

Description matt 2017-12-21 15:12:31 UTC 
Application: kontact (5.2.3)

Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.10.0-42-generic x86_64
Distribution: Ubuntu 17.04

-- Information about the crash:
- What I was doing when the application crashed:
Writing an email, clicking the "Select" button for "To:" address.
Sometimes it simply crashes.  Sometimes it crashes when I click in the search bar and start typing.  It seems to "be more likely to crash" during certain periods of time.  Not sure if that clears up over time, or after logout/reboot, or shutting down akonadi.  I'v not been able to figure that part out yet.  It's been going on for some time (quite a few months)

- Custom settings of the application:
Google Contacts (and other Google servicesin Akonadi).

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
