In Windows 10, when connecting to a server using a texturepack, an error is thrown

When connecting to a minecraft server that uses a texturepack and texture packs are enabled in the server list, an error is thrown and it disconnects you from that server. If in the server list it is set to 'Prompt' it will crash the minecraft client. See the attachment image. Error log: http://pastebin.com/99D7Zg6r
