Hi Lucas,
That looks like a case where the GLib documentation was automatically
converted to glibmm documentation, but it doesn't really make sense.
SListHandle and ListHandle types are 'intermediate' types that you
shouldn't ever really need to use.  They just provide handy
conversions to any of the standard containers.  So, you should just be
able to use either std::list<> or std::vector<> or something like
that. So something like the following:

std::list<Glib::ustring> filenames = chooser.get_filenames();

You shouldn't have to free the list at all.  That documentation is
misleading.  I've filed a bug to get that fixed:
