HTREE corruption

[Alex Bligh]

A power interruption caused an HTREE problem which appears to upset ext3
fsck.

Googling for '"Problem in HTREE directory inode" "has invalid depth"'
produces relatively few hits, and none where fsck dies.

Log below.

Running fsck manually offered the option of clearing 2 HTREE directory
inodes, which then produced a clean file system, which checks OK with
"fsck -f".

Anything to be worried about here?
