A layoutChange indicates that anything can have moved to anywhere else, including as a result purely of new items being added. It can also indicate that items are removed. The old code here incorrectly assumed that the section count remained constant over this operation by setting the size of the oldSectionHidden QBitArray - whose size is the size before the layoutChange operation - and then calling setBit with model rows numbered after the layoutChange operation. As the two are not necessarily the same dimensions, this can result in asserts from the setBit call. Simplify the handling of layoutChanged entirely by clearing section information, and using the QPersistentIndexes which indicate hidden state to restore that state after re-population.
