I managed to get the code to work properly by doing this:

In .../src/hugin_script_interface/hpi_classes.cpp (line 130) is the call
to SWIG_Python_TypeQuery. Take away the SWIGRUNTIME before the
statement, so that it reads:

    swig_type_info* swigtype = SWIG_Python_TypeQuery ( hsi_type );

I attach a patch that does this modification; it's made by hg diff.

I mistook the SWIGRUNTIME for part of the return type specification,
which it obviously isn't.

Title:
  Variables not passed to Python interface

Status in Hugin - Panorama Tools GUI:
  Confirmed

Bug description:
  Trying to pass several variables to Python script does not work.
  I'm calling hpi::callhpi with 2 argument
  hpi::callhpi( m_scriptFile.c_str() , 2 , "HuginBase::Panorama*", &pano, "HuginBase::UIntSet*", &m_images ) ;

  But in hpi_dispatch 2 HuginBase::Panorama* objects appear (and not a Panorama and UIntSet object)
  I added     
      for i in args:
          print(type(i))
  to hpi_dispatch and got:
  <class 'hsi.Panorama'>
  <class 'hsi.Panorama'>
  as result.

  And finally in the plugin only the first Panorama object appears.
  I added the same code as above to check, there is only one variable in def entry (pano,*args)
