Application: kontact (5.1.3)

Qt Version: 5.5.1
Frameworks Version: 5.22.0
Operating System: Linux 4.4.0-23-generic x86_64
Distribution: Ubuntu 16.04 LTS

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

I was reading mails inside of the "Mail" section, and I clicked the "Feeds" to read my RSS feeds. Kontact crashed instantly.

I re-opened afterwards, and retried, and this time I had no issues.

This same thing occured me some time ago

The crash can be reproduced sometimes.

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