React-Native Upgrade 0.26 "Super expression must either be null or a function, not null"

After upgrading from ReactNative 0.25 to 0.26 i get this well known error:

"Super expression must either be null or a function, not null".

I know that the most common reason is to import 'Component' from 'react-native' instead from 'react'.

But in all my components i do it right apparently:

import React, { Component } from 'react';

Has anyone experienced another root cause for this error? For now, i create a second, complete new project and try to build it up from scratch with the already existing code of the main project until the error may occur someday. But this is really a time killer....

I don't use RNMK-Library, which is known for this deprecation.

My Dependencies seems to be valid for 0.26:

"dependencies": {
    "immutable": "^3.8.1",
    "react": "15.0.2",
    "react-native": "0.26.2",

In between i found out the root cause and provided a pull request to the following library: https://github.com/Qwikly/react-native-router-redux/pull/46

(but the dependencies of this library should be updated also, i wrote about it in the comments section of the PR)
