Thanks for responding and apologies for the missteps with my reporting. I may be doing this wrong, but I'm afraid that my apport-collect attempt has failed.
Firstly, I can only ssh into the dark session on the guest. Running apport-collect requires a web browser that I must run in my host. This yields: [quote] duckhook@Zeus:~$ apport-collect 1904647 The authorization page: (https://launchpad.net/+authorize-token?oauth_token=8Gn2LstLhgmFKx5FbkCl&allow_permission=DESKTOP_INTEGRATION) should be opening in your browser. Use your browser to authorize this program to access Launchpad on your behalf. Waiting to hear from Launchpad about your decision...
