- What I was doing when the application crashed:
Just put my CF card to copy some photos.
Device Notifier popped up and I pressed the "Open with File Manager" button.
Then I browsed through the folders, pressed ctrl+A to select all of the photographs and then I pressed ctrl+t to navigate in a new tab to the directory I wanted to copy the photographs into. Dolphin crashed..

- Unusual behavior I noticed:
