I can hardly believe that, I wrote a little test app and double clicking works fine here:

###########file test.py############################################
#!/usr/bin/env python
from Tkinter import *

class Test(Tk):
    def __init__(self):
        Tk.__init__(self)
        l = Listbox(self)
        l.pack()
        l.insert('end', 'line 1')
        l.insert('end', 'line 2')
        l.insert('end', 'line 3')
        l.bind('<1>', self.dummy)
        l.bind('<Double-Button-1>', self.test)
        
    def dummy(self, event):
        return 'break'
    
    def test(self, event):
        print 'hello'

if __name__ == '__main__':
    t = Test()
    t.mainloop()

At least on my box (Python2.2/Tk8.3) the listbox behaves just like I expected.
What does the function you bound to '<Double-Button-1>'-events look like, maybe this
one is the problem here?
