-- Information about the crash:
- What I was doing when the application crashed:
I had just logged in and was waiting for the desktop to appear.
- Custom settings of the application:
I am using 4 workspaces. On one I have 1 Dolphin instance with 2 subwindows. On another I have 2 Dolphin instances with 3 subwindows each. All instances crashed.
The dolphin windows had the icon matrix for the files, no sidebar, and attached terminal windows ("F4").
