SIP and PyQt v2.4pre1 is in the usual place at
http://www.river-bank.demon.co.uk/software/private/. The main
enhancements are support for Python v2.1b1 and Qt v2.3.0-beta1.
QObject.connect() now uses the weak references introduced in Python v2.1
to manage Python slots. Before, if you didn't keep a reference to the
slot object alive (usually a class instance) and the slot was called
then you often got a seg fault. Now you don't. However, this protection
doesn't apply if the slot is a lambda function. The attached patch to
Python fixes that - hopefully this will be included in the final release
of Python v2.1.
