After the latest updates that were pushed by KDE neon user edition, I cannot get plasmashell up and running after logging in. Black screen (no background), no widgets and no panels. If I (re-)run the command "plasmashell" from the command line it crashes with an exit code of 147 and Dr. Konqi is unable to start and I get the following output: $ plasmashell Icon theme "elementary" not found. kf5.kcoreaddons.desktopparser: Could not locate service type file kservicetypes5/plasma-popupapplet.desktop, tried ("/home/cyber/.local/share", "/usr/share/usr/share/xsessions/plasma", "/usr/local/share", "/usr/share", "/var/lib/snapd/desktop") kf5.kcoreaddons.desktopparser: Could not locate service type file kservicetypes5/plasma-popupapplet.desktop, tried ("/home/cyber/.local/share", "/usr/share/usr/share/xsessions/plasma", "/usr/local/share", "/usr/share", "/var/lib/snapd/desktop") WARNING: Cannot find style "org.kde.desktop" - fallback: "/usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/Styles/Desktop" file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/Button.qml:99: TypeError: Cannot read property of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/Button.qml:99: TypeError: Cannot read property of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/Button.qml:99: TypeError: Cannot read property of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/Button.qml:99: TypeError: Cannot read property of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/Button.qml:99: TypeError: Cannot read property of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/Button.qml:99: TypeError: Cannot read property of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/TextArea.qml:941: TypeError: Cannot read property '__cursorHandle' of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/TextArea.qml:905: TypeError: Cannot read property '__selectionHandle' of null Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString) file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/ScrollView.qml:365: TypeError: Cannot read property 'padding' of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/ScrollView.qml:364: TypeError: Cannot read property 'padding' of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/ScrollView.qml:363: TypeError: Cannot read property 'padding' of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/ScrollView.qml:362: TypeError: Cannot read property 'padding' of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/TextArea.qml:905: TypeError: Cannot read property '__selectionHandle' of null file:///usr/lib/x86_64-linux-gnu/qt5/qml/QtQuick/Controls/TextArea.qml:941: TypeError: Cannot read property '__cursorHandle' of null Trying to use rootObject before initialization is completed, whilst using setInitializationDelayed.

as drkonqi isn't working can you do the following from a command line instead: "gdb plasmashell" then when it crashes type "bt" and attach that. To make coyping easier you might want to type "set logging on" just before "bt" and it will save this info to a file. Also can you cofnrim if you're running wayland or X. On the login manager the session will end in "(wayland)" if it is.
My session manager is kwin $ ps xau | grep -i kwin cyber 16704 0.3 2.2 3255264 182560 ?

If anyone can suggest a workaround, it would be very welcome. This crash is not transient. It is permanent. This is my main computer at home and I can only work with krunner at the moment.
Since I couldn't live anymore with a blank desktop, I started modifying the plasmoids that plasmashell is using directly from the config file 'plasma-org.kde.plasma.desktop-appletsrc'. What I found is that whenever I put two folderview plasmoids on any Containment of type 'org.kde.desktopcontainment', plasmashell crashes. Two interesting observations: 1) Once plasmashell is running, if I already have a folderview plasmoid and want to add an additional one there is no problem. I can add it and keep on working for this session. However, if I kill plasmashell and re-run it, then plasmashell keeps on crashing (never comes up again). If I remove manually any of the two folderview plasmoids from the configuration file 'plasma-org.kde.plasma.desktop-appletsrc' and re-run plasmashell, then plasmashell runs fine again. 2) I have a dual monitor setup and each monitor has a different desktop containment of type 'org.kde.desktopcontainment'. Let's call the containment that is assigned to monitor 1 as "c1" and the containment that is assigned to monitor 2 "c2". It doesn't matter to which desktop containment I will add a second folderview plasmoid. Any combination will occur to a crash. As long as I have one folderview in "c1" and add a second folderview in "c1", in the next login plasmashell will keep on crashing. The same will occur if I add the second folderview in "c2". It seems that as long as there is more than one folderview in one or more desktop containments, plasmashell is crashing.

Created attachment 112754 [details] New crash information added by DrKonqi plasmashell (5.12.4) using Qt 5.9.5 - What I was doing when the application crashed: I can trigger this crash one out of 10 times approximately. When I wake up my machine from standby, the third screen is disabled, so after logging in, I open the Settings Panel, navigate to "Display", activate the screen and place it and I get the crash after clicking on "Apply". This currently happens in Kubuntu 18.04 (clean install was 16.10 back then), but I had the behavior (crashing settings panel) also in 17.10, but I can't verify if the stack trace looked equal. -- Backtrace (Reduced): #6 0x00007f98cf403268 in QQuickAnimatorProxyJob::sceneGraphInitialized() () at /usr/lib/x86_64-linux-gnu/libQt5Quick.so.5 #7 0x00007f98cb8ec122 in QObject::event(QEvent*) () at /usr/lib/x86_64-linux-gnu/libQt5Core.so.5 #8 0x00007f98cc8c482c in QApplicationPrivate::notify_helper(QObject*, QEvent*) () at /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5 #9 0x00007f98cc8cc0f4 in QApplication::notify(QObject*, QEvent*) () at /usr/lib/x86_64-linux-gnu/libQt5Widgets.so.5 #10 0x00007f98cb8bc9a8 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () at /usr/lib/x86_64-linux-gnu/libQt5Core.so.5

Thank you for the report. As this was reported on an older version of plasmashell, can you please test on a recent and confirm if this issue is still occurring or if this bug report can be marked as resolved. I have set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved/worksforme" when you respond, thank you.
Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone!
This was reported with a version as new as 5.12.8 (see the latest duplicate bug). There was no indication that the bug was fixed. There is not a reliable reproducer.
No evidence of crashes in newer Plasma, and 5.12 is no longer a supported LTS version (the new LTS version is 5.18). 5.12 users should upgrade to 5.18 or newer. :)
