KDE4 plasma workspace bug

As you might already know, there is a testing version of K Desktop Environment 4 released.

It is as expected full with bugs and problems to solve. Here is one:

After you install the KDE4, try to change the wallpaper by selecting a new desktop from the ones available with the installation. For some reason it will show them properly and will allow you to save them even though they do not exist.

When you logout and restart the KDE session, you will see the Plasma Workspace application segmentation fault. It will not allow you to even view anything.

Here is a fast solution. Use the default X Desktop Environment (KDE or GNOME) or simply console to navigate to:

/home/username/.kde4/share/config

Edit or remove the file plasma-appletsrc. This is the file that is responsible for the KDE variables like wallpaper and many other. If you are not sure what to change, you can delete it – the KDE will create a new one shortly after you change any other option.
