I also downloaded the image, and what I saw was a large number of
messages of the form:

HTREE directory inode 4195634 has an invalid root node.
Clear HTree index? yes

I'm prety sure this is a result of the e2image -S (scramble) option.

Followed by "e2fsck: aborted"

It looks like the problem is fixed with the latest version of
e2fsprogs, though.  I just tried running using a build of e2fsprogs
from the next branch, and this seems to allow e2fsck to fully fix the
file system and avoid the "aborted" message.  The interesting thing is
even after it is fixed, there is something which is causing the 1.43.4
version of e2fsprogs abort:

e2fsck 1.43.5-WIP (17-Feb-2017)
Pass 1: Checking inodes, blocks, and sizes
Timestamp(s) on inode 4200169 beyond 2310-04-04 are likely pre-1970.
Fix? yes

Timestamp(s) on inode 4201357 beyond 2310-04-04 are likely pre-1970.
Fix? yes

Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information

e2fsck 1.43.4 (31-Jan-2017)
Pass 1: Checking inodes, blocks, and sizes
e2fsck: aborted

The obvious first guess is that there was a bug in the date encoding
validity checking.
