QListWidgetItem doesn't select

[graffy]

Ok,

I'm encountering a problem with the QListWidget and QListWidgetItem. Specifically, the first list widget item can't be selected if I click on the item text. If, however, I click on the blank space to it's right, I can select it just fine. The second item I can select regardless of where I click. What boggles me is that both items are constructed using the same code, so it doesn't seem to be a problem with anything I'm doing.

I'm using Qt 4.8.5, and no, upgrading to 5.x isn't an option, in case someone suggests it.

Here's a marked up screenshot illustrating the problem:

And the relevant construction code:

UserSettingsDialog::UserSettingsDialog(QMainWindow *parent) :
    QMainWindow (parent), mStackedWidget (0)
{
    setWindowTitle(QString::fromUtf8 ("User Settings"));
 
    createPage ("Display Format");
    createPage ("Window Size");
 
    connect (mListWidget,
             SIGNAL (currentItemChanged(QListWidgetItem*, QListWidgetItem*)),
             this,
             SLOT (slotChangePage (QListWidgetItem*, QListWidgetItem*)));
}

UserSettingsDialog::UserSettingsDialog(QMainWindow *parent) :
    QMainWindow (parent), mStackedWidget (0)
{
    setWindowTitle(QString::fromUtf8 ("User Settings"));

    createPage ("Display Format");
    createPage ("Window Size");

    connect (mListWidget,
             SIGNAL (currentItemChanged(QListWidgetItem*, QListWidgetItem*)),
             this,
             SLOT (slotChangePage (QListWidgetItem*, QListWidgetItem*)));
}
