--- Comment #6 from Navin <navinp1912@...il.com> ---
Grief , your inode or directory content is empty. It is corrupted also. I got
this after fixing your #1589030 with debugfs and changing fields 
directory permissions, flags to 0x1000 from your invalid value and also
changing the modify time stamp to current value from 2032.

I think this is a case where your inode field values has been corrupted or
overwritten due to some error/failure accidently. Fixing that or opening in
debugfs write mode solves the problem.  

Please close this as it doesn't seem to be related to ext4 . If you can
reproduce this using a test case from standard utilities or other ways
accessing API's please submit the test case/code. You could go ahead and
dd/write a byte that changes some struct field in the ext4 and when broken.iso
is loaded it displays errors for one/few inodes. Unless done properly with
valid values , it is not supported i guess.
