Revert changes in !1764

Description of bug

For some unknown reason the code which was setting the locale was causing failures on lxplus which I could not reproduce. Since this code was only included to address a one-off failure (that we now know how to solve) I think it's easier to revert it, so that we don't get more failures that we don't know how to solve.

@cgutsch how if you want to think of something else let me know. Since I can't reproduce the error it's hard to understand it and I have run out of ideas for checks.
