I'm not seeing it. If I try the following script I see that resizing the 
widget does update frame.winfo_width() and winfo_height. (I also see 
that the requested width and height are ignored; you can omit those).

#!/usr/bin/env python
import Tkinter
root = Tkinter.Tk()

frame = Tkinter.Frame(root, width=100, height=50)
frame.pack(expand=True, fill="both")
def doReport(*args):
     print "frame actual    width=%s, height=%s" % (frame.winfo_width(), 
frame.winfo_height())
     print "frame requested width=%s, height=%s" % 
(frame.winfo_reqwidth(), frame.winfo_reqheight())
button = Tkinter.Button(frame, text="Report", command=doReport)
button.pack()

root.mainloop()
