[PyQt] Problem with implementation of dummy (no-op) proxy model

Hi again!
I am about to give up now, but first I want to post my current code again; I
added some assertions which show an interesting fact which I have no
explanation for: One assertion fails, since I am getting a QModelIndex of my
proxy model in which internalPointer does *not* contain a QModelIndex of the
proxied model anymore, but NULL/None.
This is very strange, and with persistent QMIs, it crashes completely.
Can you confirm this, or do you know why this is so?
Maybe it is a bug/limitation of PyQt, and QMI's internalPointer() does not
increment the refcount? That would explain a lot...
This is with:
python 2.6.5 (release26-maint, Aug 18 2010, 09:33:34)
sip 4.10.5
PyQt4 4.7 (using Qt 4.6.2)
Have a nice day,
Hans
