Your code includes this sort of code a few times:

  path = g_build_filename(ustr1.c_str(), ustr2.c_str(), NULLPOINTER);
  Glib::ustring r_path(path);
  g_free(path);
  return r_path;

Surely if out-of-memory, g_build_filename() will return 0 and 
ustring::ustring() will throw a bad-argument exception, which the customer 
will not understand. We want to throw the no-memory-exception, don't we?

All the best,
Mark
