Application: dolphin (14.12.95)
 (Compiled from sources)
Qt Version: 5.4.1
Operating System: Linux 4.0.0-040000rc3-generic x86_64
Distribution: Ubuntu Vivid Vervet (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
I clicked the address bar, started typing "~/" and then when pressing the dot it crashed (I wanted to access my ~/.config folder).
It does not happen when I enter /home/kaiuwe/.config, it seems the tilde is to blame. It also does not happen on subdirectories, eg ~/foo/.bar works

This happens with the save file dialog as well, so should be assigned to its component.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
