- What I was doing when the application crashed:

When navigate the directory tree and expand or collapse a folder then Dolphin crashes.
This usually happens when the directory has hundreds of files.
It also often happens that repeated files or subfolders are displayed.

The crash can be reproduced sometimes.

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