Very funny. I think I know why: it's a highly nonlocal effect of a small
change I recently did to get rid of an old and annoying problem with
fractional translations not commensurate with FFT grid. Apparently the code
found a fractional translation 1/13 and tried to make the FFT grid
commensurate with it. Please try the attached patch
