I was wondering about this for quite a while.
I've been using ubuntu for quite a long time now, and I knew apport showed these "internal error detected" messages, without actually being noticably affected by something, but this was always in alpha/beta/RC versions of Ubuntu.
As far as I know, apport was always disabled when the distro hits release. Why did this not happen for Ubuntu 12.10? Is this a bug, or is this planned?
Nonetheless, it gives a messy impression imo
EDIT: apparantly, this was also the case for Ubuntu 12.04, and it's not apport, but whoopsie.
