My build was done on after deleting build and dist. I usually have
build/lib-win32-2.4 on my python path, i.e. I do not run the install step.
However I just discovered another thing that may narrow the problem
down. If I delete the fontManager.cache file I get the crash immidiately
on startup at the import of pylab, the only information is the same
messagebox as before.
Keeping the fontManager.cache file I reran the script for different
backends both with and without the pylab.ion() line in the script.
