According to those who have been using an Android 4.2 powered device including the new Google Nexus 4, using the app to send a text using Google Voice results in a force close message once the user starts typing the recipient's name. If you use Google Voice often and have a Samsung GALAXY Nexus that you can't wait to update, you might want to hold off until the problem is resolved before updating the phone. A quick software update in the Google Play Store should take care of the problem.
