You should call glib.variant_builder.VariantBuilder.unref on the return value when it
is no longer needed. The memory will not be automatically freed by
any other call.
In most cases it is easier to place a #GVariantBuilder directly on
the stack of the calling function and initialise it with
glib.variant_builder.VariantBuilder.init_.
Allocates and initialises a new #GVariantBuilder.
