Well, i have finally understood what the problem is. I have no idea which file 
could be causing it, it is kind of hard to imagine a problem like that could 
have a cause in one of the user's files.... 

You could try renaming ~/.local/share directory, as currently a lot of KDE 
settings reside there. But I cannot promise you will not encounter new 
problems after that...
