Qt Creator crashes when using 'create getter/setter'

If I try to create a setter using [right-click]>[Refactoring]>[Create Getter/setter] and select two variables to create setters for the Qt Creator crashes on selection of the second variable for which a setter should be created.

Let's assume the following class structure in the header:

class Foo: public QObject
{
    Q_OBJECT
public: 
    ....
signals:
    ....
public slots:
    ....
protected:
    QString m_host;
    quint16 m_port;
private:
    ....
}

Selecting the first is fine:

On selection of the second setter for m_port the Qt Creator closes/crashes.
