[wxpython-mac] Where is this "Debug" message coming from?

[Ian York]

MacOS10.5.2, Intel Mac
Python 2.5.1
wxPython 2.8.4.0

I have an intermittent bug in my program.  The action fails, but there 
is no Python error or trackback message; instead, this message is 
printed out:
[Debug] 15:26:17: wxColour::Set - couldn't set to colour string 'None'

(Or 'True' or 'False')

It looks as if the debug is swallowing the trackback I would like to use 
to find where my problem is.  (I've tried all the wx-colour type actions 
that should be getting called and they all seem to be getting valid 
input as far as I can see.)

It's not coming from my program, and I can't find the source of it, by 
e.g. grepping the wxpython library. 

Any ideas what's sending the message, and how I can override it to get 
useful information?

Thanks,

Ian
