segmentation fault in fsck

[Aphelion <aphelion@snet.net>]

The reiser4 fsck from the aug 18th snapshot as well as 0.4.11 cause a
segfault on my machine, in repair_filter_node_check. This is a clean
filesystem being checked that has never before been mounted.

Will check consistency of the filesystem on (/dev/hda1).
Will fix corruptions which can be fixed without rebuilding the tree.
Will use (default) profile.
