A DESCRIPTION OF THE PROBLEM :
Please refer to Bug ID: 6808063. I believe it was closed incorrectly (but I don't know of a way to reopen it)

I have memory capture below to show that indeed a path with space is not properly quoted: as you can see, argument to CreateProcessA is at 009727a0, and examing 009727a0 reveals that the path is not quoted. Please take a second look at it cause this something that can cause problem in some specific setups.
