Qt Version: 5.6.2

-- Information about the crash:
- What I was doing when the application crashed:

aguardando kmail mostrar mensagem. chamei o kmail, ele iniciou normal, mostrou lista de emails na tela, cliquei em um item da lista, segundos depois fechou sozinho informando erro. tem sido sempre assim faz 2 meses depois da instalar o kde neste pc.

The crash can be reproduced every time.

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