Originally reported by Anonymous

While testing with:
coverage==4.0.3
django-nose==1.4.3

With arguments:
'--cover-branches',
'--with-coverage',
'--cover-package=personalfinance.services',

I get:

File "pythonenv\lib\site-packages\coverage\data.py", line 363, in add_arcs
raise CoverageException("Can't add arcs to existing line data")
coverage.misc.CoverageException: Can't add arcs to existing line data
