Hi PySide guru's

I've a problem with a custom QListView I'm trying to make, here the problem:

I'm using QListView to show a list of QWidget object by using
this works pretty fine, but now I want to filter the item model by
using QSortFilterProxyModel()
with .setFilterWildcard() it is not working very well because the second
time the model is filtered
I got error like this :

*RuntimeError: Internal C++ object (PySide.QtGui.QLabel) already deleted.*

Without using filtering and QSortFilterProxyModel everything works fine,
but it seems I'm missing
something with the filtering operation, the indexWidget() is deleted when
using filtering :(

here a sample code where you can reproduce the bug, when list view is
shown, hit 1,2 or 3 keyboard
key to activate filtering ( Backspace to set filtering empty to show all
items )


Can someone please help me on this? is this a known bug ? or I'm doing it
completely wrong :P

Thanks in advance for your help.
