As far as I know, that behavior has existed for more than a decade (I can
confirm it even with the latest PyQt4), and QTableView was never intended
to exist without its headers, since it uses them for many aspects,
including those related to item hints/geometries and the overall viewport
size. Maybe it was different with Qt3 or earlier Qt4, but that's irrelevant
now: QTableView always has and must have two *valid* QHeaderView instances
for both its headers, it always set default ones in its private
constructor, and it's impossible to set any of them to None/null.
