Not sure why you're doubting me here Lukas. Yes, this is a problem. No 
I'm not making it up.

My understanding is that SSL is sorted before handing over to manage the 
content. As such, an incorrect or missing cert will fail, and a missing 
https server block will be handled by the default one ( or the one 
alphabetically first if not set ).

So, as stated above this is a real problem. Sure in hindsight it's a 
configuration shortfall / cockup, but it didn't occur to me that search 
engines would be attempting to force https.
