The remote file could not be transferred due to an HTTP error (400).

I keep randomly getting the error: The remote file could not be transferred due to an HTTP error (400).

I can't reproduce based on any criteria. Meaning sometimes the cache is primed sometimes it isn't, sometimes cron has just run sometimes it has been hours since last cron... it just happens out of the blue and typically only happens once for a while.

A refresh and a go again lets me transfer the image properly. I did notice that when this happens the namelookup_time has a weird value... (Float) 1.4E-5 whereas on succesfull uploads the value is something like: namelookup_time (Float) 0.000969

the rest of the $info for a failed attempt is below: I think this is a curl issue... but if you can give me any advice that would be awesome.
