pitivi doesn't work out of the box without gstreamer0.10-alsa

Release of Ubuntu: Ubuntu 10.04.3 Lucid
Package Version: 0.13.4-0ubuntu3
Expected Results: Run out of the box

Actual Results: When launch it by the first time, it will display "Could not initiate the audio output plugins
Make sure you have at least one valid audio output sink available (alsasink or osssink)", looking at Internet I discovered I had to install 'gstreamer0.10-alsa' I guess it may provide the alsasink, but not sure. So I will suggest to add it to the package as dependency.

Greetings.
