That commit "875fa64577da" does not exist. I think you are talking
about commit bd225530a4c7, which is in 6.10 and came in from your last
hotfixes pull.

I'm assuming 875fa64577da was some commit ID it had before getting
rebased or something?

I'm also a bit confused about why you mention this, since neither the
cause _nor_ the fix are in this pull request and you have the wrong
commit ID.
