I've been having the same issue today debugging kded4, though not when hitting a breakpoint but when stepping over a badly chosen expression like

            const int index = iface->metaObject()->indexOfProperty(d->property.toLatin1());
            QMetaProperty metaProp = iface->metaObject()->property(index);
            QVariant value = metaProp.isReadable() ? metaProp.read(iface) : QVariant();
            QVariant expected = d->value;

It looks like a combination of an lldb issue that's aggravated by the fact Qt Creator uses Python to control lldb. I have however been able to get out of the situation by repeating "Abort Debugging" twice, and a killall -9 of the app I was debugging.
