Application: dolphin (4.14.13)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 3.16.0-77-generic x86_64
Distribution: Ubuntu 14.04.5 LTS

-- Information about the crash:
- What I was doing when the application crashed:
While trying to drag a file to a folder, I dragged slightly too far and when the mouse reached the "address bar" where the current directory is displayed, a popup menu (list of directory suggestions) shows up and it crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
