We've changed e2fsprogs to suppress these errors when in preen (-p) mode, but in -n or in -y the messages are printed. That's because it's "good" to update the global free counts, since some people do assume that the values reported by dumpe2fs are accurate, but it's not strictly necessary from the kernel's point of view. We should probably suppress these errors in -n mode as well.
