Hi, just noticed that after the changes (mariadb instead of mysql and reinstalling akonadi-backend-mysql) kaddressbook and akonadiconsole work for a new user again.
But when adding an owncloud addressbook (DAV resource), it crashes as well with the same stack trace: Thread 1 (Thread 0xacfe1ac0 (LWP 10870)): [KCrash Handler] #7 0xb5093166 in Akonadi::Tag::isValid() const () at /usr/lib/i386-linux-gnu/ libKF5AkonadiCore.so.5 #8 0xb514024a in Akonadi::TagModel::data(QModelIndex const&, int) const () at /usr/lib/i386-linux-gnu/libKF5AkonadiCore.so.5 #9 0xb76a1779 in () at /usr/lib/i386-linux-gnu/libkaddressbookprivate.so.5 #10 0xb61ce34e in QMetaObject::activate(QObject*, int, int, void**) () at / usr/lib/i386-linux-gnu/sse2/libQt5Core.so.5 #11 0xb61ce85d in QMetaObject::activate(QObject*, QMetaObject const*, int, void**) () at /usr/lib/i386-linux-gnu/sse2/libQt5Core.so.5 #12 0xb624c741 in QAbstractItemModel::rowsInserted(QModelIndex const&, int, int, QAbstractItemModel::QPrivateSignal) () at /usr/lib/i386-linux-gnu/sse2/ libQt5Core.so.5 #13 0xb61422c9 in QAbstractItemModel::endInsertRows() () at /usr/lib/i386- linux-gnu/sse2/libQt5Core.so.5 #14 0xb51424ce in () at /usr/lib/i386-linux-gnu/libKF5AkonadiCore.so.5 #15 0xb5142c5a in () at /usr/lib/i386-linux-gnu/libKF5AkonadiCore.so.5 #16 0xb513f550 in () at /usr/lib/i386-linux-gnu/libKF5AkonadiCore.so.5 #17 0xb61cdfdb in QMetaObject::activate(QObject*, int, int, void**) () at / usr/lib/i386-linux-gnu/sse2/libQt5Core.so.5 #18 0xb61ce85d in QMetaObject::activate(QObject*, QMetaObject const*, int, void**) () at /usr/lib/i386-linux-gnu/sse2/libQt5Core.so.5 #19 0xb50ec861 in Akonadi::TagFetchJob::tagsReceived(QVector<Akonadi::Tag> const&) () at /usr/lib/i386-linux-gnu/libKF5AkonadiCore.so.5 #20 0xb50ee64a in () at /usr/lib/i386-linux-gnu/libKF5AkonadiCore.so.5 #21 0xb50ce036 in () at /usr/lib/i386-linux-gnu/libKF5AkonadiCore.so.5 #22 0xb50cef9b in () at /usr/lib/i386-linux-gnu/libKF5AkonadiCore.so.5 #23 0xb61cb0e0 in QMetaCallEvent::placeMetaCall(QObject*) () at /usr/lib/i386- linux-gnu/sse2/libQt5Core.so.5 #24 0xb61cee33 in QObject::event(QEvent*) () at /usr/lib/i386-linux-gnu/sse2/ libQt5Core.so.5 #25 0xb6a6f17a in QApplicationPrivate::notify_helper(QObject*, QEvent*) () at /usr/lib/i386-linux-gnu/libQt5Widgets.so.5 #26 0xb6a7703c in QApplication::notify(QObject*, QEvent*) () at /usr/lib/i386- linux-gnu/libQt5Widgets.so.5 #27 0xb619fc5d in QCoreApplication::notifyInternal2(QObject*, QEvent*) () at / usr/lib/i386-linux-gnu/sse2/libQt5Core.so.5 #28 0xb61a2647 in QCoreApplicationPrivate::sendPostedEvents(QObject*, int, QThreadData*) () at /usr/lib/i386-linux-gnu/sse2/libQt5Core.so.5 #29 0xb61a2a87 in QCoreApplication::sendPostedEvents(QObject*, int) () at / usr/lib/i386-linux-gnu/sse2/libQt5Core.so.5 #30 0xb61f90a3 in () at /usr/lib/i386-linux-gnu/sse2/libQt5Core.so.5 #31 0xb3b0e4e9 in g_main_dispatch (context=0xac202a00) at ././glib/gmain.c: 3203 #32 0xb3b0e4e9 in g_main_context_dispatch (context=0xac202a00) at ././glib/ gmain.c:3856 #33 0xb3b0e789 in g_main_context_iterate (context=context@entry=0xac202a00, block=block@entry=1, dispatch=dispatch@entry=1, self=<optimized out>) at ././ glib/gmain.c:3929 #34 0xb3b0e854 in g_main_context_iteration (context=0xac202a00, may_block=1) at ././glib/gmain.c:3990 #35 0xb61f9493 in QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () at /usr/lib/i386-linux-gnu/sse2/libQt5Core.so.5 #36 0xaccedd81 in () at /usr/lib/i386-linux-gnu/libQt5XcbQpa.so.5 #37 0xb619d83d in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) () at /usr/lib/i386-linux-gnu/sse2/libQt5Core.so.5 #38 0xb61a699f in QCoreApplication::exec() () at /usr/lib/i386-linux-gnu/sse2/ libQt5Core.so.5 #39 0xb64d9aa1 in QGuiApplication::exec() () at /usr/lib/i386-linux-gnu/sse2/ libQt5Gui.so.5 #40 0xb6a6f0d4 in QApplication::exec() () at /usr/lib/i386-linux-gnu/ libQt5Widgets.so.5 #41 0x80042743 in () #42 0xb5c02276 in __libc_start_main (main=0x800423f0, argc=1, argv=0xbf9f4bc4, init=0x80043f60 <__libc_csu_init>, fini=0x80043fc0 <__libc_csu_fini>, rtld_fini=0xb779a8b0 <_dl_fini>, stack_end=0xbf9f4bbc) at ../csu/libc-start.c: 291 #43 0x800428dd in _start () Rainer -- Rainer Dorsch http://bokomoko.de/
