When i go to System Settings->Workspace Appearance->Desktop Theme->Details and try to customize a theme, after pressing apply it selects a random theme and it doesn't apply the changes i did. This started happening a couple of weeks ago and it only happens in one user, the others works right, so is something about with my configuration. I tried deleting the content from ./kde4/share/apps/desktoptheme, but it didn't work. Any suggestions?
