Thanks to has for the off-list reply: I found a couple of errors in the 
sdef file.

Now my app responds to Apple Events and doesn't complain about a 
corrupted dictionary. However, I'm having some additional difficulty. It 
appears that Apple Events are bypassing the bundled Python and are going 
straight to the Tk framework instead. Tk/Aqua has pretty good 
AppleScript support, and implements a "do script" command that will 
execute Tcl scripts. My application responds to this code:

tell app MyApp
	do script "puts \"foo\""
end tell

but returns an error message for

tell app MyApp
	do script "print \"foo\""
end tell

because it's expecting Tcl code.

This is very weird, and I have no clue how to untangle it. My app won't 
respond to Apple Events at all without a valid sdef file in the bundle's 
Resources directory. However, if the sdef is present, the commands and 
Apple Events defined there are ignored and are instead handled by the 
Tcl/Tk interpreter and its sdef instead. To avoid this conflict, I've 
tried removing the Tk sdef file, and changing the Apple Event class/ID 
of my Python event to something else, but these have no effect.

It's possible to wrap Tk calls in Python code via ('root', 'tk', 
'call'), and it's also possible to force Python code to stand in as Tcl 
code via the "register" function, but I don't know if either of these 
would be applicable solutions in this instance; if the Apple Events are 
going directly to the Tcl interpreter embedded in the Tk framework, then 
it may not really be possible to send Apple Events to a bundled Python 
application using Tkinter.

Has anyone else encountered anything like this, with Tkinter or another 
toolkit?
