Eskil Abrahamsen Blomfeldt 79e0effead Fix crash in QTextDocument::clearUndoRedoStacks()
When calling QTextDocument::clearUndoRedoStacks() with UndoStack,
there were two bugs: The first was that we were retrieving
the item at "undoState" and deleting this. This is actually the
upper limit of the for loop. If the stack does not contain any
redos, then it would be == undoStack.size() and we would assert.

If there were redos, then we would delete the item at undoState
multiple times (actually undoState times).

In addition, when the loop exited, we first removed the dangling
pointers using remove() and then there was a weird resize() to
the new size minus the old undoState.

This would either assert because we tried to resize to a negative
number, or it would arbitrarily remove items from the stack.

[ChangeLog][QtGui][Text] Fixed a crash bug in
QTextDocument::clearUndoRedoStacks(QTextDocument::UndoStack).

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.
