--- Comment #4 from j...@meinkes.com --- Hm, from the backtrace it seems to be the ModemManager requesting the PIN for my SIM card that fails. If I remove the SIM card, kded5 starts and everything behaves normally including the System Tray (see Bug 417544). #0 0x00007fffe9a84c19 in ModemMonitor::requestPin(MMModemLock) () at /usr/lib/qt/plugins/kf5/kded/networkmanagement.so #1 0x00007ffff6d2846e in () at /usr/lib/libQt5Core.so.5 #2 0x00007fffe93c0522 in ModemManager::Modem::unlockRequiredChanged(MMModemLock) () at /usr/lib/libKF5ModemManagerQt.so.6 #3 0x00007fffe93c3fec in () at /usr/lib/libKF5ModemManagerQt.so.6 #4 0x00007ffff6d2026a in QObject::event(QEvent*) () at /usr/lib/libQt5Core.so.5 #5 0x00007ffff7a16362 in QApplicationPrivate::notify_helper(QObject*, QEvent*) () at /usr/lib/libQt5Widgets.so.5 #6 0x00007ffff7a1f819 in QApplication::notify(QObject*, QEvent*) () at /usr/lib/libQt5Widgets.so.5 #7 0x00007ffff6cf2962 in QCoreApplication::notifyInternal2(QObject*, QEvent*) () at /usr/lib/libQt5Core.so.5 #8 0x00007ffff6cf51c6 in QCoreApplicationPrivate::sendPostedEvents(QObject*, int, QThreadData*) () at /usr/lib/libQt5Core.so.5 #9 0x00007ffff6d4b9d4 in () at /usr/lib/libQt5Core.so.5 #10 0x00007ffff592339e in g_main_context_dispatch () at /usr/lib/libglib-2.0.so.0 #11 0x00007ffff59251b1 in () at /usr/lib/libglib-2.0.so.0 #12 0x00007ffff59251f1 in g_main_context_iteration () at /usr/lib/libglib-2.0.so.0 #13 0x00007ffff6d4b020 in QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) () at /usr/lib/libQt5Core.so.5 #14 0x00007ffff6cf14cc in QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) () at /usr/lib/libQt5Core.so.5 #15 0x00007ffff6cf94d6 in QCoreApplication::exec() () at /usr/lib/libQt5Core.so.5 #16 0x000055555555a6ad in () #17 0x00007ffff66c5023 in __libc_start_main () at /usr/lib/libc.so.6 #18 0x000055555555a9be in () -- You are receiving this mail because: You are watching all bug changes.
