Application: kontact (5.1.3)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-21-generic x86_64
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I tried to make a task inside kmail (there is a bar below to do this) after I applied it crashed.



Before that I tried to make a new task in the task part of Korganizer and this task did never show up there. It only was shown as a link in the overview tab. But the link lead me into the nothingness of tasks...

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