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.
