thanks for this! sounds like it’s specific to `update_with_media`, since it’s multipart, ie it doesn’t apply to other API POST requests? I use
[tweepy](https://github.com/tweepy/tweepy), but I’ll still keep an eye out when I get to POSSEing pictures.
I’ll be interested to know what happens with Tweepy. I glanced at its code and didn’t see any obvious special case handling, so if it works they are doing something more elegant than I am :)
