python multiline literal strings counted as missed lines

[altaurog]

I have a python project using coverage.py, reporting to coveralls.
There is a big discrepancy:
coverage.py reports coverage of 96%
coveralls reports coverage of 83%.

Drilling down, the obvious difference is that coveralls shows python multi-line strings as misses. This seems wrong to me, since the entire multiline literal was evaluated in a statement which did execute. coverage.py does not report these as misses:

How can I get the correct report from coveralls?
