setLocation()

What the hell is wrong with the setLocation function in the new Blender 2.28 release? It doen’t work anymore the way it used to be.
in 2.27 i used it this way : ob.setLocation((0.0,0.0,0.0))
but now there comes an error telling me that 3 float values were expected
I tried several other things, but nothing works.
Has anybody an idea?

PANIC!!!

I also couldn’t get shareFrom() to work.

::says here it should work::
