Application: kmail (4.13.1)
KDE Platform Version: 4.13.1
Qt Version: 4.8.6
Operating System: Linux 3.13.0-30-generic x86_64
Distribution: Ubuntu 14.04 LTS

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

My laptop was suspended. Prior to suspending Kmail was minimized to tray icon and connected to an IMAP mail account. After opening the lid (and thus resuming the laptop) after a few seconds Kmail crashed. I did not use Kmail in any way since the resume.

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