What is the hostname of your machine? If you are using Windows then you can execute "ipconfig /all" on a cmd prompt

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbb in position 0: invalid start byte

I'm going to take a stab in the dark. From the traceback, it appears Django is trying to resolve the name of the host where you are running the development server, but the byte string it is getting back from the system calls querying the host name of your computer is not encoded using UTF-8 (or is getting a character string that is not being properly encoded), hence the decode errors. 

A quick Google found this SO post: https://stackoverflow.com/questions/23109244/unicodedecodeerror-with-runserver

There are also a bunch of references to this (Still open from 2010) Python bug: http://bugs.python.org/issue9377 (socket, PEP 383: Mishandling of non-ASCII bytes in host/domain names)

Try changing the name of your computer to use only ASCII characters (which should work around the encoding/decoding issues). If that works, I'm not entirely sure what the long-term solution is, but that should at least point you in the right direction when Googling.
