Possible problem with elliptic_eu in Maxima 5.19.0

Following my previous post about an error with elliptic_e, here is 
another failure in Sage, which I believe is related to Maxima. This was 
with sage-4.1.1.rc0 with updated Maxima (5.19.0) and ecl (9.8.1)

I've don't understand what incomplete elliptic integrals of the second 
kind are, so I make no comment about

     sage: elliptic_eu (0.5, 0.1)
Expected:
     0.496054551287
Got:
     0.495848403419


I posted this as a Trac bug on Sage

If anyone could give me a Mathematica syntax to test this, I would like 
to know of it.
