Comment 56 for bug 849414

@Callum: I think the reason you and others are no longer seeing the problem is that apport -- the application which detects program crashes -- is defaulting to off now that oneiric has released.

If you would like to re-enable apport you can run the following and apport will then be active on next boot:

sudo sed -i 's/^enabled=0/enabled=1/g' /etc/default/apport
