It's been quite a while since I used these functions. They might be
buggy. I tried your example, and it failed for me as well. The problem
is related to the '--print-column' option to 'zenity'. Reading the
'zenity' documentation doesn't clear things up for me, so I'm not sure
if this is a bug in the 'zenity_list' function or what.

You can work around the problem in your example, by adding an extra
argument "all" to you function call. That is

        choice = zenity_list ("Test", {"val", "Height"}, {"TRUE",
        "FALSE"; "120cm", "180cm"}, "radiolist", "all")
