As far as I understood a value below a certain confidence value (usually
0.05 or 0.01) means the result is statistically proofed .

I tested again with Scipy 0.7.0 and the p-value was 6.00995334253e-314
the same as R's.
So, for now I assume that linregress works as it should. Also, I don't
understand why ignoring these errors is ok.
Thanks a lot
