On a new user there is an activity which is shows in the activity plasmoid but which can not be selected. Reproducible: Always Steps to Reproduce: 1. make a new user 2. log in as new user 3. look at Activities plasmoid, there is Desktop and New Activity
FWIW startkde logging suggests that the activity has the uuid 00000000000000000000000000000000 also after the first login it has no visible name in the activity switching plasmoid, on subsequent logins it will be called 'new activity'
Looks like dupe of bug 321781
The 'null' activity appears when the activity manager daemon is not running. What happens if you do a 'qdbus org.kde.ActivityManager /ActivityManager/Activities ListActivities'?
Hello! This bug report was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this bug is already resolved in Plasma 5. Accordingly, we hope you understand why we must close this bug report. If the issue described here is still present in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging Thanks for your understanding!
