Please try using apport-cli if ubuntu-bug fails, but I guess both might fail if any packages are out of date.
I'm guessing this crash is due to some extension because nobody else is reporting it, and because you seem to have so many extensions installed. And because the crashing code seems to be called directly from some Javascript. So please try removing gnome-shell extensions from the system.
