sudo apt-get update gives error when trying to add ppa repository for icecat

[user1]

I am using ubuntu 10.10 and the problem started when I tried to run:

sudo add-apt-repository ppa:gnuzilla-team/ppa

when following instructions in this place:

https://launchpad.net/~gnuzilla-team/+archive/ppa


and when I run: "sudo apt-get update" I get following error:

~$ sudo apt-get update
[sudo] password for user1: 
E: Type 'n' is not known on line 3 in source list /etc/apt/sources.list.d/
gnuzilla-team-ppa-maverick.list
E: The list of sources could not be read.

When I try to open Update Manager I get:

Could not initialize the package information

An unresolvable problem occurred while initializing the package 
information.

Please report this bug against the 'update-manager' package and include 
the following error message:

'E:Type 'n' is not known on line 3 in source list /etc/apt/sources.list.d/
gnuzilla-team-ppa-maverick.list'
