Hi everybody,

I have opensuse leap 42.1 with plasma 5.4.3. I was trying to create different activities when plasma suddenly froze as I pressed the create new activity button. First thing I did was a reboot I think, and ever since plasma freezes even when opening the activity manager widget.

If I launch plasmashell from terminal, this is the output:

Code:
kscreen: launcherDataAvailable: "org.kde.KScreen.Backend.XRandR"
kscreen: Primary output changed from KScreen::Output(Id: 67 , Name: "eDP1" ) ( "eDP1" ) to KScreen::Output(Id: 67 , Name: "eDP1" ) ( "eDP1" )

When I hover over the activities button in the system tray, I get this output:

Code:
file:///usr/lib64/qt5/qml/org/kde/plasma/core/private/DefaultToolTip.qml:48:9: QML Image: Cannot open: file:///usr/lib64/qt5/qml/org/kde/plasma/core/private/preferences-activities
trying to show an empty dialog
If I then click on it, plasmashell freezes. The output is very long (I don't know how to retrieve it all), and it ends with a long series of the following string:

Code:
qml: Switcher: QML Getting the wallpaperThumbnail
As I launch any other kind of program from terminal, I get:

Code:
 "Trying to convert empty KLocalizedString to QString."
I checked out all kinds of forums and bug reports, but I couldn't find a solution. Any help?

Thanks a lot!!
