No, gtk-qt-engine is not installed. However I had used it before it was replaced by kcm-gtk. It seems it is completely purged from my system now.
But you are right! "startkde" script removes my file (lines 189-218). It's owned by kdebase-workspace-bin - apparently it's not kcm-gtk bug. Thank you very much. :-) ** Package changed: kcm-gtk (Ubuntu) => kdebase-workspace (Ubuntu) -- kcm-gtk settings file is deleted after logout https://bugs.launchpad.net/bugs/478144 You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdebase-workspace in ubuntu. -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
