Using bus connections

Can anyone tell me what GRC is trying to tell me with this flow-graph –
it has bus connections, and it gripes. Not sure why:

Hi Marcus
It your vector to streams is set to be float output, but the time sink
seems to expect complex

Yeah, fixed that. That allows me to generate an apparently-working .py

But I still get dozens of “connection could not be made” errors when I
load the .grc file into GR (3.7.8) I was seeing the same thing on 3.7.7.
The generated flow-graph appears to be fine, but for every bus
connection, it complains about “connection could not be made”.
