The new code in after_cancel in the version of Tkinter.py
that ships with 2.3b2:

(script, type) = self.tk.splitlist(
self.tk.call('after', 'info', id))

fails because the splitlist call returns something like

('after#53',)

at least when linking against the Tcl and Tk 8.4 libraries that
Fink installs under Mac OS X.

Matthew can you test the attached patch to verify if it
fixes the problem. This (still) works for me on Tk 8.3.

Yes, the patch works fine.

With a little more investigation, I find that with Tcl 8.4 you
sometimes get back a 2-tuple and sometimes a 1-tuple. So the
comment is trivially misleading.
