Segmentation fault while trying to recover file with extundelete

hello,

I accidentally removed a directory with its contents with rm -r and I don't have a backup. I got to know about extundelete utility on linux and downloaded on my Linux Fedora 28 notebook PC. The file system is ext4. I log in to the system as single user mode and unmount the /home directory from the partition where the file was located; in this case it is /dev/mapper/fedora-home. After I unmounted /home I ran the fsck on the partition and it was successful, but when I try to recover the directory (or a single file) I get segmentation fault like this:

Code:

/ extundelete --restore-directory /home/milhan/Desktop/path/directory /dev/mapper/fedora-home
NOTICE: Extended attributes are not restored.
Loading filesystem metadata ... 3256 groups loaded.
Loading journal descriptors ... Segmentation fault (core dumped)

extundelete gave segmentation fault no matter what file I tried to recover, whether a directory or a single file, and I am certain I entered the file path correct. I did this right after the directory or file was removed. I unmounted the /home directory immediately thus avoiding any writes to the partition. Below is my filesystem:

Code:

~ df -h
Filesystem               Size  Used Avail Use% Mounted on
devtmpfs                 3.9G     0  3.9G   0% /dev
tmpfs                    3.9G   78M  3.8G   2% /dev/shm
tmpfs                    3.9G  1.5M  3.9G   1% /run
tmpfs                    3.9G     0  3.9G   0% /sys/fs/cgroup
/dev/mapper/fedora-root   50G   12G   35G  26% /
tmpfs                    3.9G  256K  3.9G   1% /tmp
/dev/mapper/fedora-home  401G   57G  324G  15% /home
/dev/sda1                976M  191M  718M  22% /boot
tmpfs                    790M   24K  790M   1% /run/user/1000

Thank you.

GIT-HTTP-FETCH(1)						    Git Manual							 GIT-HTTP-FETCH(1)

NAME

       git-http-fetch - Download from a remote git repository via HTTP

SYNOPSIS

       git http-fetch [-c] [-t] [-a] [-d] [-v] [-w filename] [--recover] [--stdin] <commit> <url>

DESCRIPTION

       Downloads a remote git repository via HTTP.

       NOTE: use of this command without -a is deprecated. The -a behaviour will become the default in a future release.

OPTIONS

       commit-id
	   Either the hash or the filename under [URL]/refs/ to pull.

       -c
	   Get the commit objects.

       -t
	   Get trees associated with the commit objects.

       -a
	   Get all the objects.

       -v
	   Report what is downloaded.

       -w <filename>
	   Writes the commit-id into the filename under $GIT_DIR/refs/<filename> on the local end after the transfer is complete.

       --stdin
	   Instead of a commit id on the command line (which is not expected in this case), git http-fetch expects lines on stdin in the format

	       <commit-id>['	'<filename-as-in--w>]

       --recover
	   Verify that everything reachable from target is fetched. Used after an earlier fetch is interrupted.
