Application: kontact (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic x86_64
Distribution: Ubuntu 13.10

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

I had just restarted the application (timeline: Noticing inbox wasn't updating, restarting Akonadi server, then restarting (closing/launching) Kontact, then Kontact crashed seconds after having relaunched and reappeared)

System: Kubuntu 13.10

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
