Version: (using KDE 4.0.2) Installed from: Debian testing/unstable Packages Compiler: gcc (GCC) 4.2.3 (Debian 4.2.3-2) OS: Linux In the file associations module in system settings, there "defaults" and "restore" buttons are always disabled, so it is impossible to restore file associations to their defaults. The same bug exists in the file associations page in konqueror settings.
Confirmed, Defaults does not work. Not sure what Reset should do so I can't really say if that works or not.
The reset button is now usable in 4.1.0. The defaults button, though, is always disabled. I guess it's not implemented...
It should have been fixed on most of the kcm modules. Can you confirm it?
I've checked almost all modules, and I've found only a couple of missing "default settings". I'll open a bug report directly against them.
