Memory leak in Tkinter.py ?

[Dr. Peter Stoehr]

Hi Python-Fans,

Greg McFarlane (the developer of Pmw) and I found a memory leak in
Tkinter.py of Python 1.5.2.

The tag_bind method of the Canvas class maintainece a dict called
self._tagcommands to store lists of function-ids returned from the _bind
call.
As far as I can see, this information not used by any other method.
Furthermore, the lists grow with every call of tag_bind and the memory
is never released.

After removing the
	if sequence and func and res:
block of the tag_bind method, the memory consumption of the enclosed
test program is constant and no longer growing.

Is it okay to remove the 
	if sequence and func and res:
block or did I miss something?

    Greetings
	Peter
