Consider the following code:

####################################################################################
template <class T> class Array
{
  public:
    void size() {}
};

template <class T> class NamedArray : public Array<T>
{
  public:
    void test()
    {
      this->size();
    }
};
####################################################################################
Kdevelop is not aware that this->size() is a member of the class Array and underlines the call red.
One interesting thing is, that inheriting from "Array<int>" instead of "Array<T>" makes Kdevelop happy.
