Making sense of a traceback from py2exe

[Jonno]

Not sure where the best place to post this is. My app uses wxpython,
matplotlib.
I'm running Python 2.7 on Windows 7.
I have a script app.py that I'm trying to turn into app.exe using py2exe.
The exe runs fine on the pc that it was compiled on but on another Win7
machine I get something like the following in the app.exe.log:

AttributeError: 'MyApp' object has no attribute 'frame'

I need some help picking apart the Traceback.

Why are there two tracebacks and which is the first to be triggered?
