I tried in a VM to provide a disk with a FAT16 partition to reproduce
this bug.  I could hit this particular error when choosing the “manual”
partitioning method and then selecting the FAT16 partition.  However I
could not reproduce the bug when choosing the “guided” methods.

I think we don’t need the installer to be able to create FAT16
partitions; we merely need it to recognize and gracefully handle them
when they exist (which I think is quite unusual: the EFI System
Partition seems to be FAT32 usually, no?).

Anyway I think this is fixed by commit
628d09ae53047ea666f4f84ae5e5be911647fe8c, which Danny just pushed.  :-)

Thanks,
Ludo’.
