C++11 thread support in Qt Creator 2.7.0 (Qt 5.0.2)

I am trying to make threads work in Qt Creator under Ubuntu. I set the

QMAKE_CXXFLAGS += -std=c++11 -pthread -lpthread  
CXXFLAGS += -std=c++11 -pthread -lpthread

but it still wont work and will write

terminate called after throwing an instance of ‘std::system_error’ 
  what(): Operation not permitted

The file I try to compile is this

#include <iostream>
#include <thread>
using namespace std;

void fun(){
}

int main()
{
    thread th(&fun);
    cout << "Hello World!" << endl;
    return 0;
}

I had to add the following line to the myProject.pro file

LIBS += -pthread

so it works now with these two lines

QMAKE_CXXFLAGS = -std=c++11 
LIBS += -pthread
