Comment 4 for bug 119661

Even worse when it chokes on bootstrap:

adi@xubVM:~/blah$ python2.4 bootstrap.py
While:
  Initializing.

An internal error occured due to a bug in either zc.buildout or in a
recipe being used:
Traceback (most recent call last):
  File "/tmp/tmpI0XdJV/zc.buildout-1.1.1-py2.4.egg/zc/buildout/buildout.py", line 1476, in main

HTTPError: HTTP Error 404: Not Found

The thing is that ``extends`` in the buildout.cfg pointed to an invalid URL.
