There have been some wxWidget/wxPython bugs that could account for this  
problem, but neither of the ones I submitted below actually led to an  
assert.

If you want, you can wait for wxPython 2.5.2.3 to be released or try  
the wxPython-dev developer preview and see if it fixes the problem.

Of course, there could be a bug in PythonCard, but that sounds unlikely  
given the error you reported.

If the image can't be handled by wxWidgets, then I would like to get it  
from you, but don't email it to the list. Send me an email offlist with  
the size of the image and we'll figure out how to transfer it so I can  
reproduce the problem.
