[David]

Steps to reproduce:

 * Configure apt-listchanges to display output in terminal
 * Switch to TTY 1 (command line), run update

What should happen:

Displays output in TTY 1

What happens instead:

Error reported.

Notes:

 * Running an update in TTY 7 (desktop) displays output in new terminal window (correct behaviour)
 * Obviously requires update to include changes
