Title:
  apport-gtk crashed with SIGSEGV

Status in apport package in Ubuntu:
  New

Bug description:
  I am not 100% sure this is related but I have been unable to run an X
  session on Ubuntu 20.04 in a virtual machine. I have tried VirtualBox
  and virt-manager (KVM/QEMU). This has been the case for a few months
  now. The Wayland session does work.
