The underlying Qt connection stays alive, but on the PyQt side the
connection goes down making the Qt connection just call the universal
slot object without being forwarded to python.

It does. SIP handles instance methods (and lamba's AFAIR) specifically
to avoid being dependent on a temporary wrapper object.
I spent considerable time digging into this (although without knowing
much about the C API to Python).
If you still think I'm wrong, I could try digging back and posting
some source code references.
In any case, you should be able to reproduce the connection problem at
your side with the example Kevin posted.
FYI, these are my platform specs in case this is somehow platform
o Mac OS X 10.5.2
o PyQt-4.3.3, Qt-4.3.3
o SIP 4.7.3
o Python-2.5.1 (the built-in version)
We are Elektropeople for a better living.
