Dear KDE SIG, In the CMake cache variable for KDE4 (in kdelibs at least), there exists a cache variable named "KDE_DISTRIBUTION_TEXT" with default value "compiled source". That string is used by the KBugReport dialogs (see file kdeui/dialogs/kbugreport.cpp in kdelibs-4.0.1, line 213). It should be better, in Fedora packages, to set it to "Fedora packages", or perhaps maybe "Fedora package %{name}-%{version}-%{release}". I propose that change to be applied to %{cmake_kde4} in /etc/rpm/macro.kde4, so that all rebuild will have that change: -DKDE_DISTRIBUTION_TEXT="Fedora package %{name}-%{version}-%{release}" (I have not tested my proposal.) Debian packages use "Debian packages", and Ubuntu packages strangely use "Kubuntu packages". See for example http://archive.ubuntu.com/ubuntu/pool/universe/k/kde4libs/kde4libs_4.0.1-0ubuntu1.diff.gz
Ubuntu packages using "Kubuntu packages" is not strange, Kubuntu is just Ubuntu's KDE spin, they use the same repositories, so the packages you're seeing at archive.ubuntu.com are maintained by the Kubuntu team and are the ones which end up in Kubuntu releases. But yes, setting KDE_DISTRIBUTION_TEXT sounds like a good idea to me.
Will be in builds >= 4.0.1-8
