more exactly “underlying C/C++ object has been deleted" error.

In my experience, those errors are easy to resolve: just assign the new object to something, so it isn't immediately deleted. A little awkward, maybe, and it shouldn't happen, but if that's the worst quirk of PyQT/PySide, I can deal.

Those errors are always related with a bad implementation where there is something holding a reference to the qt python object represented by the bidding therefore keeping it alive even when their c++ instance has been already deleted. The solution is to go back to the drawing board and improve the implementation :)
