All right, I managed to upload it with chunked uploading just now, so I’m closing this as invalid. (Not sure if that’s correct, feel free to change it if needed.)

I had already tried chunked uploading yesterday, but it failed with a strange error message so I figured it doesn’t work. Sorry for the noise.
