Vegard,

How big is the filesystem?  Is there any chance you can make a
compressed e2image of the file?  (This will not include file contents,
but does reveal the names of the file.)  Given the nature of the bug
which you are reporting, it should be safe to scramble the names of
the filenames using the -s option if that would make you feel more
comfortable.

The quick version is:

    e2image -r /dev/loop0 | bzip2 > badfs.e2i.bz2

Then folks like Josef would be able to test your filesystem right
away, instead of asking oyu to test it.

					- Ted
