Application: kmail (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
I started Kontact and KMail crashed before the ui was visible.
- Unusual behavior I noticed:
Since the recent update from Kubuntu to 13.10 KMail is startet as a separate window when I launch Kontact. This is probably not related because KMail did not crash since a long time but you never now… ;)

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
