Here is the list of packages that would be removed on my system if i allow full-upgrade to upgrade libqt5core5a
libpoppler-qt4-4 libqt4-dbus libqt4-declarative libqt4-designer libqt4-help
libqt4-network libqt4-script libqt4-scripttools libqt4-sql libqt4-sql-sqlite
libqt4-svg libqt4-test libqt4-xml libqt4-xmlpatterns libqtassistantclient4
libqtcore4 libqtdbus4 libqtgui4 pdfviewer python-qt4 python-qt4-dbus
So for now I'm not doing full-upgrade
And I have still not allowed libsqlite3-0 to upgrade as I think this will break firefox. Appears the fix for this is in progress, but not completed.
