difficult to tell why it should segfault on that line:
(gdb) print smeta
$1 = (const QMetaObject *) 0x7f96ea4b5a00 <QDBusServiceWatcher::staticMetaObject>
(gdb) print *smeta
$2 = {d = {superdata = 0x7f96ef758ec0 <QObject::staticMetaObject>, stringdata = 0x7f96ea4a2140 <qt_meta_stringdata_QDBusServiceWatcher>,

static_metacall = 0x7f96ea49b3c0 <QDBusServiceWatcher::qt_static_metacall(QObject*, QMetaObject::Call, int, void**)>,
relatedMetaObjects = 0x0, extradata = 0x0}}
(gdb) print sender
$3 = (const QObject *) 0x7f966800b5d0
(gdb) print *sender
