This may result in incrementing an invalid iterator after the
iterator's container has changed. Also, for this to happen,
the view needs to have an active editor.
The reentrant call happens as follows in QTreeView, after the
model adds new rows to the view:
QTreeView::rowsInserted()
QAbstractItemView::rowsInserted()
QAbstractItemView::updateEditorGeometries()
QTreeView::visualRect()
QAbstractItemViewPrivate::executePostedLayout()
QTreeView::doItemsLayout()
QAbstractItemView::doItemsLayout()
QTreeView::updateGeometries()
QAbstractItemView::updateGeometries()
QAbstractItemView::updateEditorGeometries()
Other concrete item view classes may be prone to the same issue.
The fix consists in relayouting the items if needed, which should
trigger calling updateEditorGeometries() again. This doesn't
invalidate previous optimizations regarding item relayouting since
we only force relayouting when it'll be done by visualRect().

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
