This means that the /usr/lib/thunderbird/extensions -> /usr/lib /thunderbird-addons/extensions symlink is broken on your install because there are unsupported packages installing files in to /usr/lib/thunderbird/extensions. It's likely this has always been broken on your install. The difference here is that lightning moved to /usr/lib /thunderbird-addons/extensions with this update as a consequence of us merging the Thunderbird and Lightning sources
