I finally got some time to sit down and play around with the giomm stuff
tonight, but unfortunately I haven't gotten very far yet.  I can't even
get a simple example to run.  Has anybody else written any test/sample
programs with giomm? Am I doing something wrong here?

$ cat giomm-test.cc 
#include <giomm.h>

// no overloads exist without a cancellable argument yet, so create a
dummy NULL
// cancellable
Glib::RefPtr<Gio::Cancellable> not_cancellable;

int main (int argc, char** argv)
{
    Gio::init();
    Glib::RefPtr<Gio::File> f = Gio::File::create_for_path
("/home/jonathon/tmp/giomm.cc");
    Glib::RefPtr<Gio::FileInputStream> stream = f->read
(not_cancellable);
    return 0;
}

$ ./giomm-test 
Segmentation fault (core dumped)

gdb says:
