I'm using quantal and I can confirm it still happens. (I'd mark the bug
as affecting me too, but LP is timing out consistently)
Using apt version 0.9.7.5ubuntu2.

[MASTER] Update fails with invalid package files with "Encountered a
section with no Package: header"
Status in “apt” package in Ubuntu:
Status in “apt” source package in Natty:
Status in “apt” source package in Precise:
Status in “apt” package in Debian:
Binary package hint: adept-updater
Pertinent data printed when attempting to run Updater as follows:
An unresolvable problem occurred while initializing the package
Please report this bug against the 'update-manager' package and
include the following error message:
'E:Encountered a section with no Package: header, E:Problem with
package lists or status file could not be parsed or opened.'
Remove problematic files from /var/lib/apt/lists/ and rerun apt-get update.
In the event that one is connected to a network with a proxy server
that returns html pages (like a web page requesting you to login) and
not package list files. Those html files will get downloaded to
/var/lib/apt/lists/ and prevent someone from using a package manager
until the problem html pages are removed.
1) Ensure /etc/apt/sources.list points to archive.ubuntu.com
2) Setup proxy server to block access to archive.ubuntu.com and return something like http://people.canonical.com/~brian/tmp/not-packages.html
3) Execute 'sudo apt-get update' in a terminal
4) Observe the following:
'E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_natty_main_binary-amd64_Packages
E: The package lists or status file could not be parsed or opened.'
5) Try 'apt-cache policy apt' and be sad that it doesn't work
6) run 'sudo rm /var/lib/apt/lists/*Packages' to clear the error.
With the proposed package installed repeat steps 1 to 3.
4) Observe the following:
''Get:1 http://archive.ubuntu.com oneiric InRelease [189 B]
Ign http://archive.ubuntu.com oneiric InRelease
E: GPG error: http://archive.ubuntu.com oneiric InRelease: The following signatures were invalid: NODATA 1 NODATA 2'
5) Try 'apt-cache policy apt' and be happy that it works
