at() member list autocomplete broken

Up to Creator 2.5.2 this works :

struct MyStruct
{
double a;
QString b;
}

int main(int argc, char *argv[])
{
QVector<MyStruct> v;
v.at(0). // would show the member list (a,b) of MyStruct
QVector<MyStruct*> pv;
pv.at(0). // would turn the . into -> and show the member list of MyStruct
}

In Creator 2.6 betas this no longer works. This also affects QList.
