------------------------+---------------------------------------------------
Reporter: mguaypaq | Owner: AlexGhitza
Type: defect | Status: new
Priority: minor | Milestone: sage-4.4.1
Component: algebra | Keywords: FractionField, subs

------------------------+---------------------------------------------------
!PolynomialRing elements allow keyword arguments when substitute values
for the variables (via !__call!__), but the corresponding method in
!FractionFieldElement doesn't handle keyword arguments properly.
