CTree bug or programmer error?

["Andrew P. Lentvorski" <andrewl deliverator io com>]

I created a sample app which just creates a simple CTree(1.1.12).  The bug
I am seeing is that gtk_clist_columns_autosize does not set the width
of the column wide enough to see the entire label.  Is this a bug or
did I just make a stupid programming error?  Does a gtk_ctree_columns_autosize
function exist which does better (I don't see one in the gtkctree.h file)?

Sample app attached below.
