What were you doing when the application crashed?
This is reproducible: Open evolution. Open a new message (to send). Type in an address or a subject or something else - just that it is not in "unchanged" mode. Now go back to the main window and use File > Quit. Evolution crashes reproducibly. Usually evolution asks what to do with the unsent message.
