Testcase appearsAndSort failed when running the complete testcase but not as single test. More irritating was the fact that the error was in QAbstractItemModelTester::headerDataChanged() but the affected test did not change any header nor does it use the blamed model... The reason for this is, that QAbstractProxyModel emits a queued headerDataChanged signal when the header item count changes and therefore only evaluated when the event loop is run. Fix it by calling processEvents() after the rowCount change in filterColumns().
