Description Fred Jackson 2017-11-05 10:21:29 UTC 
Application: kmail (5.2.3)

Qt Version: 5.9.2
Frameworks Version: 5.37.0
Operating System: Linux 4.13.0-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
- What I was doing when the application crashed:
I updated some information on one of my identities which caused an error creating several empty identities . after removing these identities and updating the the ones I use, I can no longer compose email. 
Trying to compose an email causes kmail to close/crash after I typ in a few characters of the 'To' address.

The crash can be reproduced every time.

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