I have to apologize here. Looking at the code I posted in my previous
message I noticed that I had pasted one of the two functions wrong.
That function wrapping an int was just a test that i later removed.
The true function that causes the problem is the following:

SWIGINTERN void
TagLib_List_Sl_TagLib_String_Sg__each(TagLib::List<TagLib::String >
*self){
=09static swig_type_info *desc =3D SWIG_TypeQuery("TagLib::String" " *");
=09TagLib::List<TagLib::String>::ConstIterator i;
=09for (i=3Dself->begin(); i!=3Dself->end(); ++i)
=09{
=09=09VALUE x =3D SWIG_NewPointerObj((void *) &(*i), desc, 0);
=09=09rb_yield(x);
=09}
}

Which uses a pointer type (TagLib::String), for which I already
defined a typemap that looks like this:

%typemap(out) TagLib::String {
=09if ($1.isNull()) $result =3D Qnil;
=09else $result =3D rb_str_new2($1.toCString());
}

I will read the rest of your message and try your suggestions later
tomorrow as it's quite late here and I sure I will mess something else
up if I don't get some sleep.

Thanks again and sorry for the mistake.
