Version: 4.1.87 (using Devel) OS: Linux Installed from: Compiled sources After importing a color scheme the apply button is still disabled. You need click on a other scheme and then back to imported scheme to apply it, this is a little bit annoying.
Here using: Qt: 4.4.3 + qt-copy-patches-889120 KDE: 4.1.87 (KDE 4.1.87 (KDE 4.2 >= 20090101)) kdelibs svn rev. 904849 / kdebase svn rev. 904849 on ArchLinux x86_64 - Kernel 2.6.27.10 I can confirm this bug.
