Sentry Crash Report:

Description Freek de Kruijf 2017-01-08 11:29:55 UTC 
Application: kontact (5.4.0)

Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.9.0-2-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I moved three messages from the GMail IMAP server to a folder on another IMAP server, not on localhost, based on dovecot. After that I selected the destination folder, but I am not sure this was the cause of the crash or the previous move.

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