-- Information about the crash:
- What I was doing when the application crashed:
I generally make use of Dolphin in detailed tree view  and split view mode. Recently when in split mode, if I attempt to collapse an expanded folder it crashes immediately. But never occured when I expand a folder.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
