The bug was in the gallery app itself; a review is open; with luck,
should land an hour or so after approved.
Given how it was fixed; I don't understand how it worked before though...

One last closing comment; the click updater "app" doesn't seem to
filter per framework as I get them as updates for my devel install
which doesn't have the new framework; luckily they fail to install as
the framework required doesn't match the provided one :-)
