Are you using the e2fsprogs-interim patchset version
e2fsprogs-1.39-tyt1? It should only be used for ext4dev development,
and nothing else. I'll look at fixing that bug in
e2fsprogs-1.39-tyt1, but that code base has a bunch of interim patches
that I'm currently in the process of reworking for e2fsprogs mainline
inclusion; it's there only for the convenience of ext4 developers.
I've added a README to make this clear for future users.
