Incorrect code generated for implementing members of templated classes

Consider a simple template class:
 

namespace ns
{
template<typename T>
class MyClass
{
public:
    void bar();
    void foo(T arg);
};
}

When using refactoring on foo() to generate the implementation of the method outside the class the Qt Creator generates the following incorrect code:
 

template<typename T>
void MyClass::foo(ns::T arg)
{
}

There are two problems with this:
1) The template argument is missing in the class name. It should be

MyClass<T>::

2) The name of the namespace is being inserted as a qualifier for the template argument for some reason (this does not happen when the class is NOT in a namespace). It should be

MyClass<T>::foo(T arg)

Furthermore if I generate the implementation for bar() AFTER foo() the previous method's beginning is incorrectly detected and the template line ends up above the new definition like this:

template<typename T>
template<typename T>
void MyClass::bar()
{
}

void MyClass::foo(acore::T arg)
{ 
}

This requires a lot of manual fixing after generating the code.
