Comment 6 for bug 657505

This is still a problem in 12.04 64-bit. I've run f-spot from Terminal and this is the output:

(f-spot:3435): GdkPixbuf-WARNING **: GdkPixbufLoader finalized without calling gdk_pixbuf_loader_close() - this is not allowed. You must explicitly end the data stream to the loader before dropping the last reference.
Exception in Gtk# callback delegate
  Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.
