Bug 368753

Application: dolphin (15.12.3)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-36-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed: had mozilla and chrome running, nothing else. Openned dolphin and navigated on my folders, crashed repetedly even after restart, update and upgrade of packages.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Bus error
