UnreadablePostError: request data read error

Steps to reproduce:

* Throttle your internet connection to eg 10kbps down/10kbps up
 * This not required but I haven't managed to abort the connection before the server accepts the request.
 * Maybe if you try to upload a really large picture you will have enough time to abort the connection.
* Upload a new picture to your profile
* Hit "Update information" button
* Before the request gets POSTed completely, stop loading the page (x button in awesome bar)
* Error gets raised


I suggest we skip this for now since this is more of an apache issue of how it handles file uploading when a connection error occurs. Also i don't think this affects the user experience somehow.
