Status in linux package in Ubuntu:
  Won't Fix

Bug description:
  Kernel oups while apt-get upgrade in maverick daily build 2010.09.09. 
  Steps to reproduce:
  1. using virtualbox-ose on ubuntu 10.04 as as host, start maverick: 
ubuntu-desktop-i386.iso (daily-live/20100909)
  2. try ubuntu without installation / english
  3. root@ubuntu:~# apt-get update
  4. dpkg -l > pre.txt
  5. root@ubuntu:~# apt-get upgrade
  just after downloading new packages, you will see the crash icon in tray.
  6. dpkg -l > post.txt

  See $(diff pre.txt post.txt) from attachment to find packages which may did 
that. 
  My guess it this may be one of apt-* but not sure.
