kde-4.5 automatically creates lots of junk activities

[Dennis Schridde]

Whenever I start kde-4.5, the activity selector will display lots of junk activities. The names of these range from "Start" (my regular search&execute activity is also named "Start") to "unnamed". These activities usually seem to be newspaper-activities.
When I delete them, they will reappear upon next start of KDE.
Such unwanted activities will also still appear after deleting .kde/share/config/plasma*. (I am atm not exactly sure whether the activities appearing then are the exact same ones.)

plasma-desktop just exited in a possibly unrelated crash. After starting it again from the commandline, I get even more activities, all also called "Start". They all seem to be empty newspaper activities. The "unnamed" activity mentioned earlier is a search&exec one. One of the "Start" thingies seemed to be a duplicate of my real "News" newspaper activity.

It is a bit difficult to measure the exact configuration of each activity, because apparently the activity selector is easily confused by switching between them. The first time I tried to display the activities in a row, it worked fine and they were shown on the desktop. Now, upon clicking them in the selector, the desktop will show the empty newspaper for *all* of my activities, even for those which were correct.

This is using kde-4.5 from kubuntu-ppa/backports.

I managed to get some more information after a reboot:
* "Start" - Newspaper - showing the plasmoids of my original "News" activity, but all unconfigured
* "unnamed" - S&E in default configuration (konqueror, kmail, systemsettings, dolphin)
* "Start" - empty newspaper
* "Start" - empty newspaper
* "Start" - S&E as I configured it
* "Start" - empty newspaper
* "Start" - S&E in default configuration
* "News" - newspaper as I configured it - broken layout, especially for Facebook plasmoid (the website is displayed outside of the plasmoid, in a small square)
* "Start" - empty newspaper

The order these activities appear in seems to be randomised on every start, and some activities labelled "Start" seem to be added upon every start of KDE.

It seems that producing a plasma-desktop crash or removing activities will create more activities on the next start of KDE. (Maybe some recovery mechanism running wild?)

Currently I have mostly "unnamed" and empty activities, a few "Start" newspaper activities. My original "Start" S&E activity, however, is entirely gone.

I have a similar problem.

I have 4 virtual desktops (just normal Desktop activities) with a different activity (widgets, wallpaper) each.

When I open the activity manager there are at least 10 random extra activities. If I delete them manually they reappear on next login.

This can't be good for system resources...

Same here.
