Package: e2fsprogs
Version: 1.44.5-1

When attempting to defrag with e4defrag, I see the following error message:

> [root@Printers ~]# e4defrag /
> e4defrag 1.44.5 (15-Dec-2018)
> ext4 defragmentation for directory(/)
> zsh: segmentation fault  e4defrag /

I have tried running e4defrag via bash, dash, and zsh, and I get the same 
result each time.

What should happen: e4defrag should defrag any ext4 partition. My system uses 
ext4 exclusively.
