Bug 354567

Application: dolphin (4.14.2)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.2 (jessie)

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

My Dolphin had several tabs opened on some directories, on disks in ntfs and other in ext4.
I was creating a symbolic link of a file on a ntfs disk in a tab, on a ext4 disk opened on another tab of Dolphin.

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