David did use scale_C=False...
I can reproduce the error by adding the following test to test_multiclass.py:
def test_ovr_fit_predict_svc():
ovr = OneVsRestClassifier(SVC())
pred = ovr.fit(iris.data, iris.target).predict(iris.data)
assert_equal(len(ovr.estimators_), n_classes)
print ovr.score(iris.data, iris.target)
git bisect tells me that the regression was introduced in:
https://github.com/scikit-learn/scikit-learn/commit/658897497399147a78fad5f7001fc62dd1e487ed
decision_function in SVC is lacking tests !
