Here is some more information.

If I do this:

   QFont font = label->font();
   font.setBold(true);
   label->setFont(font);

Then the text shows up (but only for the bold labels).

But, if at the very start of the program I do something like this:

   QFont font("Lucida Grande", 11);
   QApplication::setFont(font);

Then no text shows up either, including the bold ones that did before.

But so far this has only happened on this one machine. This sounds like 
one of those things that is going to be impossible to reproduce.
