0.4.1: source tar contains a lot of precompiled files

The [0.4.1 tarball]( http://pypi.python.org/packages/source/a/astropy/astropy-0.4.1.tar.gz) contains a lot of .pyc files which create some formal difficulties for Debian: "lintian" complains f.e.
```
E: python-astropy source: source-is-missing astropy_helpers/astropy_helpers/__pycache__/__init__.cpython-32.pyc
E: python-astropy source: source-is-missing astropy_helpers/astropy_helpers/__pycache__/__init__.cpython-33.pyc
```
Especially the files in `__pycache__` seem to be there on accident only, right? Could they be dropped from the source distribution?
Optimal would be to drop all .pyc files.
