Application: dolphin (17.12.2)

Qt Version: 5.10.0
Frameworks Version: 5.43.0
Operating System: Linux 4.13.0-36-generic x86_64
Distribution: Ubuntu 16.04.4 LTS

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

I had multiple tabs open, one of them was a folder with a torrent I downloaded (using deluge) with an open text file.
When I deleted the torrent (from deluge) all the files were deleted except the text file I had open, when I closed the text file dolphin crashed.

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