I can not reproduce this very clearly but it happened to twice today and many times yesterday, I will try to figure out the exact steps to reproduce and post it here. Backtrace is useless because of no Qt debug symbols.. but nothing I can do about that at moment Thread 1 (Thread 0x7f2bf46c57c0 (LWP 9125)): [KCrash Handler] #6 0x00007f2bf26eb7f4 in QQuickItem::isVisible() const () from /usr/lib/libQt5Quick.so.5 #7 0x00007f2bf26eed42 in QQuickKeyNavigationAttached::setFocusNavigation(QQuickItem*, char const*, Qt::FocusReason) () from /usr/lib/libQt5Quick.so.5 #8 0x00007f2bf26ef0a1 in QQuickKeyNavigationAttached::keyPressed(QKeyEvent*, bool) () from /usr/lib/libQt5Quick.so.5 #9 0x00007f2bf26f4f8e in QQuickItemPrivate::deliverKeyEvent(QKeyEvent*) () from /usr/lib/libQt5Quick.so.5 #10 0x00007f2bf26f50e5 in QQuickItem::event(QEvent*) () from /usr/lib/libQt5Quick.so.5 #11 0x00007f2bf0641acc in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /usr/lib/libQt5Widgets.so.5 #12 0x00007f2bf0646f10 in QApplication::notify(QObject*, QEvent*) () from /usr/lib/libQt5Widgets.so.5 #13 0x00007f2befb48d1b in QCoreApplication::notifyInternal(QObject*, QEvent*) () from /usr/lib/libQt5Core.so.5 #14 0x00007f2bf26eb921 in ??

Oh, this turns out to be easy one 1) open kicker 2) search something 3) clear search field (using backspace keys) 4) press up/down arrow keys 5) crash
(In reply to Bhushan Shah from comment #1) > 2) search something I should mention that you have to search something which opens Desktop Search/Bookmarks column.
