merging an fork with the main repository in git

I have fork-ed arora and i had added some very small changes
the problem is to update my repository and merge the changes already done on the main one

I go to my local cloned repository (the forked one is in my github account)
I use fetch to check what is changed vs my repository


$ git fetch git://github.com/Arora/arora.git master

watch the log
$ git log -p HEAD..FETCH_HEAD

or with gitk

$ gitk HEAD..FETCH_HEAD

I have added an remote repositry (so we have less typing)

$git remote add icefox git://github.com/Arora/arora.git

$ git fetch icefox

From git://github.com/Arora/arora

 * [new branch]      master     -> icefox/master

$git merge icefox/master

Removed src/locale/pt_BR.ts

Then i tried to push the changes in my forked repository

git push origin master
To git@github.com:mariuz/arora.git
! [rejected] master -> master (non-fast forward)
error: failed to push some refs to 'git@github.com:mariuz/arora.git'

seems that i have made some changes in the repository at github that i didn't got them down

$ git pull
