Application: kontact (4.14.3)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 3.19.0-43-generic x86_64
Distribution: Ubuntu 14.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I closed some sub windows in akregator as kontact crashed.

Akgregator was pretty slow closing the windows

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