-- Information about the crash:
- What I was doing when the application crashed:
I was exploring one single password protected samba share with two windows opened in different folders. Before, the two windows was minimized and hovering the folder icon in the bottom bar showed me the grayed preview selection of the two. Hovering one of the two windows, the red close options showed. Clicking on the red x to close one dolphin crashed

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