Ok never mind on that. recent release has the same problem.
so this is 2.6.33-rc7 ...
you had:
[ 347.673207] EXT4-fs error (device hda4): make_indexed_dir: invalid rec_len for '..' in inode 425166
(wish we'd print out the actual bad rec_len there ...)

Not sure what's going on with the duplicate 0-inode entries there yet.
