There must be something else in the code your not showing (the code you
posted did not work out of the bx...)  This works:-

#### start

from Tkinter import *

class myUI:
    def __init__(self, root):
        self.listbox = Listbox(root,
            selectmode=SINGLE,
            exportselection=0)
        self.listbox.pack()
root = Tk()
UI = myUI(root)


def handlerfunc(event):
    print event.widget.get(first=event.widget.curselection()[0])

UI.listbox.insert("end", "1")
UI.listbox.insert("end", "2")
UI.listbox.insert("end", "3")
UI.listbox.insert("end", "4")


UI.listbox.bind('<ButtonRelease-1>', handlerfunc)

root.mainloop()

#### end


Tested just a few seconds ago on a RedHat Linux 8.0 Python 2.2.2
Tk 8.4 and Python 2.2.2 Tk 8.3
