If the "2.4.0+..." above corresponds to the LablGTK release, then it
is not current - a newer release has been out for two months.  You
could just grab the current source tree at

http://wwwfun.kurims.kyoto-u.ac.jp/soft/olabl/lablgtk.html

and build it locally... builds are pretty smooth, even for Windows! :)

Also, do not overlook the "examples" directory tree - the file
combobox.ml shows uses of combo_box_text.  Note that the default item
is being set explicitly just after creation, plus the tuple nature of
the constructed value.
