I've noticed that that command runs frequently when unnecessary, but
I'm surprised that it causes a problem. Are you pushing and popping
patches? Now that we're putting the repository version into the
binary, when you push and pop, this changes. I have noticed that this
runs sometimes even if you change nothing in the repository. Are you
pushing/popping or anythign like that?
