Subject: dumpe2fs/dump/restore not working correctly for ext4?

Hi,

I need to look into this more obviously and try other dumps etc, but I 
even tried extracting a single (smaller) directory and it also segfaulted, 
has dump been tested properly with ext4?

# restore -f ../p34-root-2010-03-02.ext4dump -r .
Segmentation fault (core dumped)
