I came across this too recently, because of a bug in the efivar package that affects some platforms: https://github.com/rhboot/efivar/issues/111 So I downgraded it in 887fe1fbde7d72788ec348ab4665e1df3d0d704f. Which commit did you run the reconfigure command on? A bigger problem is that GRUB will happily wipe the bootloader entry, proceed to try to make a new one which fails, and then exit with status code 0. I wonder if this has been reported upstream.
