This could be caused by a corrupted directory on disk. This patch
should do a better job of detecting what the problem is. You should be
able to fix the problem by running "fsck -f" against the partition.
I don't know what the cause of the corruption may be. I'd be interested
if it is reproducible after fixing it with fsck (assuming fsck does fix
it).
