Description Chris 2017-08-15 13:45:58 UTC

Application: kontact (5.5.2)

Qt Version: 5.9.1
Frameworks Version: 5.37.0
Operating System: Linux 4.4.79-4-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
Normal startup from locked screen.  Received the crash report and then Kontact/Kmail startedup.  This has happened several times, so my indication that it happens always might be a little too much.  Suffice to say it is happening more frquently since up dating to 17.04 as in atlest twice per day.

The crash can be reproduced every time.

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