Note that the Qt version doesn't yet show a progress bar.  I'm experimenting with a different API for the progress bar, 
where you always call the "create" routine before the loop, and call the "update" routine on every trip through the 
loop and have it decide when to pop up the progress dialog, and, although I need to do more work on it, it might be 
that the extra procedure call is sufficient to slow down the file-loading process, so it might be that some of the 
difference between the Qt and GTK+ versions is less work done in deferred_create_progress_bar() and possibly even less 
work done in update_progress_bar().
