Subject: e2fsck -D segfaults in pass 3A

After playing around with e2fsck (today's git of the "pu" branch) a bit 
more, I still cannot use -D on this filesystem. I've tried with earlier 
version, but it still dumps core in pass 3A (Optimizing directories). I've 
compiled e2fsprogs with "CFLAGS="-g" ./configure --enable-htree; make", 
too get a few more results when this happens. Running under gdb gives:

(gdb) run -Dfv /dev/md4
Starting program: /opt/e2fsprogs/sbin/e2fsck -Dfv /dev/md4
e2fsck 1.40.7 (28-Feb-2008)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 3A: Optimizing directories

Program received signal SIGSEGV, Segmentation fault.
0x08065bb9 in ino_cmp (a=0x8898fe90, b=0x898feb0) at rehash.c:173
173	rehash.c: No such file or directory.
 	in rehash.c

The full backtrace: http://nerdbynature.de/bits/e2fsprogs.pu/e2fsck-1.40.7-Dfv.log

The filesystem in question has been created in 11/2007 - maybe I missed 
some on-disk changes since then and have to recreate the fs?

Thanks,
Christian.
