qdbusxml2cpp breaks with multiple interfaces and -c

Create a header file like

#ifndef FOO_H
#define FOO_H

#include <QObject>

struct Foo : public QObject
{
  Q_OBJECT
  Q_CLASSINFO("D-Bus Interface", "org.cmake.Test.Foo")
public:
  Foo();

signals:
  void mySignal(int in);

private:
  static int foo();
};

struct Bar : public QObject
{
  Q_OBJECT
  Q_CLASSINFO("D-Bus Interface", "org.cmake.Test.Bar")
public:
  Bar();

signals:
  void barSignal(int in);

};

#endif

Run qdbuscpp2xml on it to create an xml file.

Run qdbusxml2cpp on the xml file, passing the -c option. C++ files generated have two different classes defined with the same name (as specified with -c).

There should be sanity checking when using qdbusxml2cpp -c that there is only one interface.

There should be a recommendation that only one interface should be defined per file for input to qdbuscpp2xml.
