probably fixed with r820991 if this bug is related / a duplicate of bug #163673
The code in question from qdbusintegrator.cpp; QDBusErrorInternal error; q_dbus_bus_add_match(connection, hook.matchRule, error); if (!!error) { QDBusError qerror = error; qWarning("QDBusConnectionPrivate::connectSignal: received error from D-Bus server " "while connecting signal to %s::%s: %s (%s)", hook.obj->metaObject()->className(), hook.obj->metaObject()->method(hook.midx).signature(), qPrintable(qerror.name()), qPrintable(qerror.message())); Q_ASSERT(false); } and as the error-message sayed, this is actually a problem with your configuration since no more dbus-connections are allowed. Probably the Q_ASSERT is wrong there cause it should imho not crash/assert in such a case. But well, it's in any case an upstream-bug aka not related to KDE and therefore I close the report.
