Bug 361949

Application: kontact (5.0.2)

Qt Version: 5.5.1
Operating System: Linux 4.2.0-35-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
- What I was doing when the application crashed:
Rebooted the computer which I had closed the evening before, without specifically closing Kontact (assuming that this is a possibility of Kubuntu: switching off the computer and then rebooting and restarting right where one had left).

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
