Description
http://bugs.python.org/issue1242657 continually bites users of Django: see #14766, #2705, #13204, #7786. Also see http://groups.google.com/group/django-developers/browse_thread/thread/cf2b76a9b69f794c/ac09404089bfd185.
The basic problem is that certain versions of Python swallow exceptions in __len__, causing various weird QuerySet behaviors. We've mostly worked around these in the test suite by skipping tests on particular Python versions, but this doesn't help users who see weird stuff on their side.
We need to add some sort of "Python version notes" document (similar to the database notes) that document this problem (and another others we know of). We should probably also add a link to the install notes to pre-warn people on OSX -- one of the affected versions is the Python that ships with 10.6.

Closing given the lack of activity here and the fact that this was an issue on Python 2.6 which won't be supported in Django 1.7.
