New submission from Niklas Sombert :
Today I tried to access URLs like this one: http://user:1...@example.net:8080.
The result was this:
>>> import urllib.request
>>> urllib.request.urlopen("http://user:1...@example.net:1234/";)
Traceback (most recent call last):

So, urllib seems to have problems parsing HTTP URLs which contain a userinfo
part. (Requests works.)
