To have sddm and plasma session QML stuff work correctly:

qtdeclarative-opensource-src 5.7.1~20161021-5

for the fix you need at least libqt5qml5 and libqt5quick5 5.7.1~20161021-5.

So wait till apt-cache policy shows the required versions for these *and* you 
can safely apt dist-upgrade without removing a ton of packages.


To fix quassel:

plasma-integration_5.8.2-1+b1_amd64

which Dmitry aka mitya57 also just uploaded.


I´d say tomorrow, maybe even earlier, depending on buildd speeds.


I suggest you monitor #debian-qt-kde IRC channel. Can have benefits as mitya 
provides links to packages he built there, so on my system Quassel client is 
also already fixed.

Ciao,
