Application: kmail (5.4.0)

Qt Version: 5.7.0
Frameworks Version: 5.29.0
Operating System: Linux 4.9.0-2.g6fbc0c0-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
After KDE openSuse Tumbleweed repo-update to version 16.12.x, KMail remains unusable:

- What I was doing when the application crashed:
Starting KMail from the KDE-Desktop / from console.

- Unusual behavior I noticed:
KMail isn't working either when started within Kontact: I can see my folders and message list, but the content of the messages is not shown, even if I select one from the list. I see the KMail-Greeter-Screen instead. Trying to create / send a new mail or to move / copy / delete one results in a Kontact crash.  Maybe this is an Akonadi-problem, too? The contact list shows the same behaviour.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
