I have a partition raw image on which I am trying to run extundelete to undelete some files from an ext4 filesystem. Unfortunately extundelete exits with a segmentation fault.
Is there anything I can do?
root@ubuntu-VirtualBox:~# extundelete --restore-all mmcblk0p7.raw WARNING: EXT3_FEATURE_INCOMPAT_RECOVER is set. The partition should be unmounted to undelete any files without further data loss. If the partition is not currently mounted, this message indicates it was improperly unmounted, and you should run fsck before continuing. If you decide to continue, extundelete may overwrite some of the deleted files and make recovering those files impossible. You should unmount the file system and check it with fsck before using extundelete. Would you like to continue? (y/n) y Loading filesystem metadata ... 218 groups loaded.

dmesg gives only:
