Description of Issue/Question

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x18 pc=0x12d6855]

Setup

terraform {
  required_version = "~> 1.1"

  required_providers {
    libvirt = {
      source  = "dmacvicar/libvirt"
      version = "~> 0.6"
    }
  }
}

provider "libvirt" {
  uri = "qemu+ssh://davidalger@hylfing/system?sshauth=privkey&socket=/var/run/libvirt/libvirt-sock"
}

resource "libvirt_volume" "fcos35" {
  name   = "fcos35"
  source = "https://builds.coreos.fedoraproject.org/prod/streams/stable/builds/35.20211203.3.0/x86_64/fedora-coreos-35.20211203.3.0-qemu.x86_64.qcow2.xz"
}

Steps to Reproduce Issue

Simply run terraform plan with the above configuration. It's specifically triggered by including sshauth=privkey in the uri as otherwise it defaults to attempting agent authentication.

Error: The terraform-provider-libvirt_v0.6.12 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

2021-12-29T11:11:29.166-0600 [DEBUG] provider: plugin exited

Additional information:

My private keys all have a passphrase on them. I believe by default it would be using the one at ~/.ssh/id_rsa but it panic also occurs when including keyfile=/Users/davidalger/.ssh/id_ed25519 in the uri value. I stumbled upon this panic while figuring out why agent authentication wasn't working. Since my keys have passphrases on them, I wouldn't expect this to plan out correctly, I would expect the error noted in the debug log to be presented rather than crashing the provider:

Failed to parse ssh key: ssh: cannot decode encrypted private keys
