Bubbles in coolant may definitely indicate a head gasket leak. But make sure the water pump is not leaking air in at the seal. Especially with a partly clogged radiator, there is an increased tendency to pull air into the system at the water pump seal or any possible leak in the radiator core or lower hose/pipe connections.
I've seen head gasket leak cases where the coolant looked fizzy with tiny bubbles, almost like beer. Rusty coolant often indicates a head gasket leak.
