Bug 366414

Application: dolphin (15.12.3)

Qt Version: 5.5.1
Operating System: Linux 4.1.27-27-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: I moved files from one folder to an other folder (with two instaces of dolphin). Also deleting files in both dolphin windows. Normally the crash occurred after a deletion operation. The number of moves and deletions are more than 50 files each. After restarting dolphin the problem after the next >= 50 file deletions.

The crash can be reproduced every time.

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