QSortProxyModel isnt notified when the sourceModel dies

[tuli]

Hey,

I have a QSortProxyModel that leeches off another model that I set with setSourceModel().

When the sourceModel is destroyed, but the QSortProxyModel is still attached to the GUI, it ends up showing ugly empty rows (see screenshot). At this point, sourceModel() method returns NULL and my overriden rowCount() in the QSortProxyModel also returns 0.

But it looks like this isnt enough, I guess this should trigger a reset_model signal, which it seems isnt done automatically when the sourceModel dies.

Am I expected to monitor the lifetime of the sourceMOdel on my own? Seems unnecessary, and I already take care of rowCount().
