Some index terms not appearing correctly

[Mark Summerfield]

Hi,

I'm working on a book's index but a few terms are not coming out
correctly. I've produced a cut-down example that produces this index:

    addAction() (QWidget), 2
        QWidget, 2
    hasFocus() (QWidget), 2
    () (QWidget), 2
    QWidget (QtGui), 2
        addAction(), 2
        hasFocus(), 2
        (), 2
    scaling, widgets, 1
        scaling, 1

What should be output is this:

    addAction() (QWidget), 2
        QWidget, 2
    hasFocus() (QWidget), 2
    width() (QWidget), 2
    QWidget (QtGui), 2
        addAction(), 2
        hasFocus(), 2
        width(), 2
    scaling, widgets, 1
        scaling, 1

I assume that I've somehow made a syntax error that isn't bad enough to
force lout to terminate, but is bad enough that lout fixes it wrongly.

If anyone can tell me how to fix this I would be very grateful!
