Error when populating lazily QListView

[Bakuriu]

I'm using a custom model class in a QListView.
My model class implements also canFetchMore and fetchMore, so that it should load lazily the data.
But it seems like it is not working properly because every 2-3 or 4 fetchMore I get this error:

StdErr: QTreeView::rowsInserted internal representation of the model has been corrupted, resetting.

StdErr: QTreeView::rowsInserted internal representation of the model has been corrupted, resetting.

To copy to clipboard, switch view to plain text mode 

Reading that error seems like the model sometimes has to load again all the previous data due to some fact that i don't know...
anyone know a way to avoid this error?

Your model is buggy. maybe http://labs.trolltech.com/page/Proje...view/Modeltest helps you finding those.

Ok I'll try it.

Edit:
I'm working with Python not with C++ so it is useless.
In fact I don't know almost nothing of C++ and looks like Qt doesn't work with it on my pc(it cannot find the headers not even if I put the complete path to them...)
