eclipse - EGit: cannot push, cannot pull

Question

I'am using EGit and I commited a change to my local git repository.

I'd like to push this change to a remote. When doing that, a dialog screen pops up which shows "rejected-master-master-non-fast-forward". The answer of this linked question states that I have to pull first.

When doing the pull, an EGit exception is thrown:

org.eclipse.jgit.api.errors.TransportException: Nothing to fetch.

It seems that I'm stuck. Who can help me out?

UPDATE

The .git/config file in my repository contains (remote URL hid):

[core]
  repositoryformatversion = 0
  filemode = true
  bare = false
  logallrefupdates = true
  ignorecase = true
[branch "master"]
  remote = origin
  merge = refs/heads/master
[remote "origin"]
    url = <URL_HIDDEN>

I'm using Eclipse Git Team Provider 3.4.1.201406201815

The configuration of the repository seems to miss this line in the [remote "origin"] section:

fetch = +refs/heads/*:refs/remotes/origin/*

It tells git to fetch all refs starting with refs/heads/ (all branches) and store them under refs/remotes/origin/ locally. E.g. the refs/heads/master in the remote repository will become refs/remotes/origin/master locally (or origin/master in short).

Can you add that and try if it makes pull work?

Also, it would be very interesting to know in which way you first created/cloned this repository.
