Sentry Crash Report:

Description picolino 2016-08-23 11:40:50 UTC 
Application: kmail (5.2.3)

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

-- Information about the crash:
- What I was doing when the application crashed:
step to reproduce the crash :
  - new message
  - fill the TO field with text
  - remove the text 
  - right click into the field and select configure completion
no panel does open and kmail crash instantaneously

- Custom settings of the application:
 autocompletion using recent adresses and indexed dadresses can be enabled or disabled, it doesn't change the outcome.
I use a caldav adress book, it is the first in the completion order.
I use Kmail since less than a week, the autocompletion never worked

The crash can be reproduced every time.

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