Oh, OK, that did the trick, thanks! I've ended up with something like
this:

%module TraceObject
%{
#include "TraceObject.h"
%}

struct TraceObject
{
// Manually hack in some Python code to save a reference to the
// constructor arguments. This prevents the Python string
// disappearing while the C++ TraceObject object has a
// pointer into it.
%feature("pythonappend") TraceObject {self.saved_init_arguments = args}

    TraceObject(char const *);
    // ...
};

Couldn't find any docs on this though (I've got swig-1.3.27). Grepped
everything for pythonappend and only matched Source/Modules/python.cxx
