Which exact error message? If it's:

  /usr/sbin/grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged.

... then you'll get that any time you try to install GRUB to a partition rather than the MBR, unless the filesystem on that partition reserves space for boot loader code (basically, btrfs). The warning doesn't indicate a problem that would prevent your system booting next time round, but rather a general unreliability of this setup against things like aggressive fsck implementations.

It's only related to this bug if you're also getting "error: non-sector-aligned data is found in the core file".
