I'm against using subversion URLs in buildouts.

Be that as it may....

Unfortunately, setuptools and urllib2 are often not very helpful with  
the exceptions that raise.  By the time buildout gets an exception,  
the useful information is often not available.

Yup. You'll actually get a traceback and you can get into pdb and see  
what URL is being fetched.

You can also try using the -v option to see what package is being  
loaded when the error occurs.

I encourage you to report miss-raised  exceptions to the responsible  
party. For example, I expect that you'll find that the URL is knows to  
setuptools and that you can submit a setuptools bug to include the URL  
in the exception. (Of course, if buildout can generate a more helpful  
error, I'd be happy to fix it.)
