So far the patches seem to have fixed the issue I long had sending empty lines randomly.

Here are my replies to your questions.
1) erc-send-whitespace-lines was set to nil
2) Hmm no I don't have nothing quite unusual on erc that i can think of now. I have erc-nl-nicks.
3) Yes exactly nothing unusual about that.
4) I will since it seems to have "fixed" the issue so far. I will keep that in mind in case it happens again.

That one case was the only until now. Didn't happen again and I've tried to reproduce but would never happen, so I'm not sure if it really matters. I will keep testing.
