nbd-client dies when running passwd in chroot

[Derkades]

Hi, I encountered a bit of a strange problem. I am using nbd-client version 3.25.

My steps:

• nbd-client -name test 10.0.1.1 /dev/nbd0
• mount /dev/nbd0 /mnt/fedora: /dev/nbd0 contains an ext4 filesystem with a Fedora system
• chroot /mnt/fedora
• passwd: returns segmentation fault
• It is no longer possible to use the mounted file system

In dmesg:

I can share the block device contents if needed.
