Hi,
I haven't had a proper look (just got out of bed :) , but I remember
seeing behaviour like this a while ago in my first attempts at Gtk.
Are you setting up a renderer in the combo box to show the text, and
have you packed it properly? Not sure if that's the problem here, but
it's the mistake I made and looked the same ('empty' drop down that
was the right length).
