In the coverage report for Coverage, there are lines for:
build\bdist.win32\egg\simplejson\__init__
build\bdist.win32\egg\wsgi_xmlrpc\__init__
They each point to their own file (build_bdist.win32_egg_simplejson___init__.html for example), but the contents of the file are for a different source file. It starts with "Coverage for c:\ned\coverage\trunk\test_init_.py: 100%". test_init_.py is also in the report, and also says this at the top.
