keyTangent query call bust?

Hi all, I’m just wondering if any of you have hit a bug in the keyTangent call in Maya 2016.5, it looks like the args are no longer getting passed in correctly to the call when in Query mode, works in 2016 ext1 but bails in 2016.5, wonder if any of you had hit the same thing and/or had a work around?

import maya.cmds as cmds
cube=cmds.polyCube()[0]
cmds.setKeyframe(cube,t=0)
cmds.setKeyframe(cube,t=10)
cmds.keyTangent(‘pCube1.tx’, q=True, t=(0, 10) , itt=True, ott=True, ia=True, oa=True)

thanks

Mark

yea we noticed the same thing, the MEL version of the command still works.
