Bug 374325

Application: dolphin (16.12.0)

Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.8.13-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Navigating on multiple tabs open to different folders of the same file system. I had Okular open on several pdf files, opened from dolphin (by double click).

- Custom settings of the application:
* Double click to open files and folders
* Details view mode
* Several local and remote places added to the side bar
* Information view open
* Files sorted by name, descending order

The crash does not seem to be reproducible.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
