Error while importing overrided module

Hi!
I'm creating a plugin manager system 'pluginmate' for Python (with ideas based on pyutilib pca and envisage).
(you can find it here, but it is in early, development stage: https://github.com/wdanilo/pluginmate)

When importing the main module, the sys.modules['pluginmate'] is overriden with a class instance. Maybe this is not beautifull, but it gives me some cool features.

The problem is, when running tests, everything works if .pyc files are not generated. After they are generated I've got error. Full error stack can be found here: http://bpaste.net/show/65558

The problem does not exist after running tests the first time after changing the 'libs/utils/moduleUtils.py' file (the file responsible for overriding the module), so the error is connected with some kind of .pyc files caching by py.test

cant be replicated on python 2.x

you might want to add arguments to super() calls so it can be executed on older pythons

i suppose we need to investigate if python3 broke something wrt importing again

additional interesting effect - if import pluginmate is added at the top of the module, it works on python3.2

I think this could be closed. There is no sufficent test cases for that, and the architecture of pluginmate do not need more such functionality and everythink works as should. If in the future we will see this bug again, it will be reopened.
