Version: (using Devel) Installed from: Compiled sources OS: Linux As explained in more detail in http://bugs.kde.org/show_bug.cgi?id=159047 the "Defaults" button doesn't work as expected: [...] Notifications -> System Notifications NO [6] [6] neither does the Reset button in both tabs [...]
Now (current KDE 4 trunk), the "defaults" button works for the "player settings" tab, but not for the "applications" tab. The "Reset" button works instead on the "applications" tab but not on the "player settings" tab.
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug. Kcontrol has been replaced by System Settings in Plasma. Please give the latest version of that a try, and open a new bug in "systemsettings" if you continue to have an issue. Thank you!
