--snip--
I did the install of canberra to try to fix it. So before this, it had other complaints.
Please advise. I prefer not to run it with all errors going to /dev/null.

You may see by the history that I changed this after finding out xdg-open is a script, I nailed down it was executing "gio", which I provide the version for above with the issue file dump.

Looks like I don't have the package right. Google AI says libglib2.0-bin, but launchpad rejects that. Could be Glib, or GIO is a helpful starting point. Since I started with xdg-utils, I will leave it as that.
