documented function `' was not declared or defined bug?

Hi,
I'd like to ask if following doxygen behaviour is a bug?

Let's have two files myclass.h and myclass.cc.
--------------------
#ifndef MYCLASS_INCLUDED
#define MYCLASS_INCLUDED  ///< Multiple inclusion protection.

/**
 * @brief Documentation of class.
 */
class MyClass
{
  public:
    /**
     * @brief Documentation of method.
     * @param myParameter Documentation of parameter.
     */
    void myMethod(unsigned int);

  private:
    unsigned myProperty;  ///< Documentation of property.
};

#endif  // MYCLASS_INCLUDED
--------------------
#include "myclass.h"

void MyClass::myMethod(unsigned myParameter)
