If you do not understand the error message and the error is in Python 
code, you can go look at the code in the file to get a better idea.  In 
this case, the 'raise' statement is almost certainly preceded by an if 
statement.  See what condition was checked that your input would fail. 
If necessary, you can edit request.py to add print statements (what I 
would do, after copying to request.bak) what args are actually passed to 
open_unknown_proxy.  Or try pdb (which I never have).
