KDE 4.6.5 "experimental test" repo update alert
A new version of gtk+2, a version of gtk+3 and some updated supporting libraries (atk, pango, vala, d-conf, gdk-pikbuf, gail) will be showing up in the "experimental test" repo this evening.
Upgrading gtk2 messes up the look of some apps (including Dolphin) until you reboot. Restarting KDE may suffice but I haven't tested that.
If you have an upgraded KDE box using the "main.mepis-deb.org/mepiscr/kde/ experimental test" repo which you treat as a stable production machine you may want to skip these updates at least until there's been some further testing.
You may also want to reread the previous sentence looking for the inherent contradiction.
