What were you doing when the application crashed?
I clicked on the File -> Print... menu item for the second time since the application 
was opened.

After force quitting the application, I am no longer able to restart it from the terminal.
Strace'ing the application gives the following at the end of the strace output:

testuser@home:~$ 

This is the exact behavior I have seen with another application that crashed (totem).
