[Bug 1649270] Re: Crash in gnutls_x509_privkey_import_pkcs8()

[Nikos]

I believe that this is related with this bug
https://gitlab.com/gnutls/gnutls/issues/148

that was fixed only in 3.5.x branch. I've backported it to the 3.4.x branch at:
https://gitlab.com/gnutls/gnutls/merge_requests/188

Title:
  Crash in gnutls_x509_privkey_import_pkcs8()

Status in gnutls28 package in Ubuntu:
  Confirmed

Bug description:
  $ git clone git://git.infradead.org/users/dwmw2/openconnect.git
  $ nm-connection-editor

  Add a Wifi connection, use EAP-TLS and click the button to select a
  private key. Navigate to the openconnect/tests/certs/ directory. Watch
  it segfault instead of displaying the contents of that directory in
  the file browser.

  Thread 1 "nm-connection-e" received signal SIGSEGV, Segmentation fault.

  Apologies for lack of debugging symbols; it wasn't clear how to install those. And it's trivially reproducible on Ubuntu 16.04.
