Description TYY331 2018-05-30 19:47:32 UTC

In a recent update the desktop fails to start.
Plasmashell can't initialize correctly due to an error in libactivityswitcherextensionplugin.so:

/usr/bin/plasmashell: symbol lookup error: /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma/activityswitcher/libactivityswitcherextensionplugin.so: undefined symbol: _ZN11KActivities15ActivitiesModelC1ERK7QVectorINS_4Info5StateEEP7QObject

Workaround: move the file so plasmashell doesn't find it, the desktop is able to start but activities, desktop wallpaper and icons are disabled, but the panels and widgets work.
in a TTY type:
sudo mv /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma/activityswitcher/libactivityswitcherextensionplugin.so /usr/lib/x86_64-linux-gnu/qt5/qml/org/kde/plasma/activityswitcher/libactivityswitcherextensionplugin.so.bak

The error appeared in a recent plasma-desktop update 4:5.12.5+p16.04+git20180530.0845-0

Fixed in git, see https://commits.kde.org/kactivities/df518a3b65bcb704085700bf10f962380c61bacf

Depending on how much packages need to be re-compiled and re-published, it could need some time until the fix reaches users.

CC'ing neon maintainer. Maybe it is possible to push updates manually to make this process faster.
