Bug 356762

Application: dolphin (15.08.3)

Qt Version: 5.5.1
Operating System: Linux 4.2.6-1-CHAKRA x86_64
Distribution: "Chakra"

-- Information about the crash:
It crashes when I select file with a mouse drag. In this case the file are not in the top level folder of the view (i.e. it shows a tree, and these files a few levels down) and in the course of the drag I cause the window to scroll.

The crash can be reproduced every time.

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