Yes, it's an actual problem with the usual idiom for registering GLib types.
Until it is fixed in GLib, we work around it by trying to ensure types get
registered from known single-threaded locations. In this case, a call to the
get_type method in the plugin init or class initialisation for the mad
element should do it.
