When a QTextCursor survives its QTextDocument, the internal QTextDocumentPrivate pointer is set to null. There are checks for this in all the QTextCursor functions to skip out early if such a QTextCursor is used. However, when executing the "if (d->priv)" condition in setters, this will access the non-const operator->() of QSharedDataPointer and detach the QTextCursorPrivate, and in the copy constructor of this class, there was an unprotected call into priv->addCursor(). In theory, we could cast all the checks for d->priv to avoid detaching, but in practice this doesn't matter, since the setters will typically detach anyway later on. [ChangeLog][QtGui][Text] Fixed a crash that can happen when calling a setter on a QTextCursor after its QTextDocument has been deleted.

README
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.
