I think this is known, but I can't remember whether it's been reported or not; certainly I have run across very similar behavior in the past as well. I think that some things related to this are because our fast evaluation routines do not know how to handle z.real() and friends, but that may be changing in the next (4.3.2) version of Sage. Mike H., Jason G., Robert B. - any comments?
