Liro the QA team do the best they can to test updates before they go to
stable, but you hit a diferent issue, there is not enough people testing
packages before going to stable.
My keyboard layout is spanish, most QA people have a English keyboard
layout, I can update and I do not note the missing layout, so it is valid
for me to say than the package "work for me" because it does, I do not
change the desktop layout after a update, you hit a issue than can be
easily identified by a user of this layout but it was not a tester of this
layout, you can help this thing of issues to no become a stable update in
the future, criticizing do not help to much.
