Perfect, thanks for the details. (And I'm sorry it's wearing you down.)
There's a bug having to do with secur32 and certificate caching, bug 27168, and I wouldn't be surprised if there's a similar bug with wininet. You could have a look if attachment 36923 [details] has any impact.
I'll have another look at the log in the meanwhile to see if there's anything that sticks out.
That patch from 36923 doesn't help. Nothing interesting in logs still one cert and chain validation still fails.
