After I upgraded KDE to version 4.13.0 Kontact now segfaults on starting. KDEPIM is masked to stay at 4.4.11. Here is the backtrace: Application: Kontact (kontact), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1". [KCrash Handler] #5 0x0000003047797756 in QObject::connect(QObject const*, char const*, QObject const*, char const*, Qt::ConnectionType) () from /usr/lib64/qt4/libQtCore.so.4 #6 0x00007f744de2c4d6 in KontactInterface::Plugin::part() () from /usr/lib64/libkontactinterface.so.4 #7 0x00007f744e3d72b0 in Kontact::MainWindow::selectPlugin(KontactInterface::Plugin*) () from /usr/lib64/libkontactprivate.so.4 #8 0x00007f744e3d65f4 in Kontact::MainWindow::loadSettings() () from /usr/lib64/libkontactprivate.so.4 #9 0x00007f744e3dc0af in Kontact::MainWindow::initObject() () from /usr/lib64/libkontactprivate.so.4 #10 0x00007f744e3dc71d in Kontact::MainWindow::MainWindow() () from /usr/lib64/libkontactprivate.so.4 #11 0x00000000004044c4 in _start () The various component apps (KMail, KAddressbook, etc) still work correctly. I then recompiled kontact-4.4.11.1-r1 and now the Kontact Introduction page appears but I get a similar segfault as soon as I select a plugin to show: Application: Kontact (kontact), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

"kontact (4.12.5) on KDE Platform 4.13.1 using Qt 4.8.5" why don't use kontact 4.13.1 on kde 4.13.1 ?
Because after KDE 4.4 KDEPIM became unusable and everything I have read indicates nothing has changed.
Ok so it's not supported and we never fixed it. so I close as wontfix
