Description smihaila 2015-12-04 16:00:46 UTC 
1. Open System Settings.
2. Go to "Application Style".
3. Select "Window Decorations".
4. Download additional scheme/theme, such as Oxygen KDE4.2.2 or Oxygen DLS (can't recall exact name because I can't go there anymore without crash)
5. Select the newly installed scheme. Hit ok.
6. Get back to "System Settings" main window.
7. Try to get back to "Window Decorations." The "System Settings" app will crash.

This has happened due to selecting a mix of settings, or clicking the "fine tune" tab of "Window Decorations" but not actually changing anything. Can't recall 100% how I got into this state.

The bottom line is that now I can no longer invoke the "Window Decorations".

Reproducible: Always

The latest apt-get update + upgrade done via KUbuntu 15.10 brought my plastma-desktop to version 5.4.2. How to get the 5.4.3? Should I manually add some dev-grade PPA repositories in order to see the 5.4.3? If so, could you please advise what PPA to add?

Thank you.
