Well, I don't know why but plasma configuration files are changed broken my backup script. Unfortunatelly I discover this new behaviour when plasma enter in and infinite loop of crashes after a software update.

Yes, I know, I know, I'm an unlucky man because Plasma is rock solid and don't crash but I must have a hard life . So, this is a warning for other unluckys who is backing plasma configuration files before changing something or updating.

The new files are:
plasma-desktoprc
plasma-desktop-appletsrc

Another thing, when I do a right click in a Folder View with a nepomuk filter plasma crash. Can anybody confirm this problem to report bug in bugs.kde.org?

The same for python plasmoids. Magic Folder, crash plasma and I don't know if is a problem in my system or I must report the bug so feedback are wellcome .
