QLineEdit::setText() emits QLineEdit::textChanged(), which is connected to QComboBox::editTextChanged(). When a user slot connected to editTextChanged() sets QComboBox::editable to false, the line edit will be deleted in setEditable() and when control returns to QComboBoxPrivate::setCurrentIndex(), the formerly non-null 'lineEdit' has changed to nullptr, leading to a nullptr dereference when attempting to set the completionPrefix on lineEdit->completer(). Fix by re-checking 'lineEdit' after returning from the QLineEdit::setText() call. Add a test.

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.
