Problem in Match Rotation

[geoath]

hi!
has anybody faced this problem?
let's say i have null1 and null2.
null1 is animated and i want to match it's rotation with null2
when i run the command it doesn't get the global rotation of null2, it keeps it's current value..

if i also try to copy-paste,let's say, the global rotation x from null2 to global rotation x in null1 (in the transform panel) the result is ..additive!!!!!

no problem at all if the object i want to match it's rotation is not keyframed!!!
also note that there is no problem in match transform and match scale..

i can't remember if i had this problem in version prior to 2010sp1

thanks in advance

ps: if someone wants to try it
-create 2 nulls, set a keyframe in null1, give a rotation to null2
-match rotate null1 to null2
-null1 "flashes" as for a fraction of second it rotates to null's2 value, then returns to it's current value..
