Please don’t do that. It will be re-added later. > However, Sam seems to report a more general > problem.

There are already several packages relying on the "namespace packages" feature. The problem is when you have two modules, named foo.bar and foo.baz, shipped in two different packages. If each of them shipped foo/__init__.py, they couldn’t be installed together, and this is why the empty __init__.py needs to be generated automaticaly. > Josselin, any hint on this problem?

We’ve already discussed the issue on IRC before sam reported the bug, and I still think the bug lies in python-twisted. Shipping modules in the site-packages directory without making them available to the user through 'import' is a clear abuse of the python API. Of course it is possible to work around that bug in python-support by adding a specific exception for python-twisted, but this is a last-resort measure, and I don’t want to do this when it is so easy to fix twisted, by removing the __init__.py check that was recently added by upstream.
