I would love to get my hands on that filesystem and be able to run
e2fsck under gdb to figure out what's going on.  This looks like
something entirely new.  Unfortunately this is so bug that e2image
will probably create a truly huge file that will take forever to

Is there any possibility I can get remote access to the machine, or
perhaps if that's not possible you can run it under a debugger, maybe
under some kind of remote VNC connection so I can see what you're
seeing and a telephone call so we can work this problem together?
