Looks like Gst::ValueList::get() calls Glib::Value::init() which
should only be done once. Since you are in a loop, it is done more
than once. Looks like the glibmm doesn't have g_value_unset() wrapped.
You can put g_value_unset(mag.gobj()) at the top of your loop. Or you
can put the the GLib::Value<float> mag declaration at the top of your
loop.
