The size for the directories are 0 instead of 4096 and those directories
have no contents. An ext2ls on /usr in this example:

EXT2 rev 1, inode_size 256
ext4fs read 0 group descriptor (blkno 1 blkoff 0)

ext4fs read 1760 group descriptor (blkno 14 blkoff 3072)

Note only debug messages are printed. Not even '.' or '..' entries.

It's only a problem when it is the /boot directory which seems to be
random from install to install.

Just defined DEBUG on ext_common.c and ext4fs.c. It happens either way.

Yes, I'll have to recreate one with a reasonable size.
