So an update on this, I decided to reflash combined.
2 days 17 hours later hildon-home bug is back, however I have some more information.

I woke up early this morning and was checking up on my TMO active topics for about 40 minutes.
My alarm clock went off and it acted really slow to silence.
Then "hildon-home not responding" checked top and low and behold it's back. Had to killall h-d to get any response back.

I am thinking is maybe connected to alarmed or my alarm clock, will do some more testing.
