Another clazy bug, clazy-range-loop

```

for( QString : slstKeys ) {.   Missing reference in range-for with non trivial type (QString) [clazy-range-loop]  c++11 range-loop might detach Qt container (QStringList) [clazy-range-loop]

```

The list is populated and having debugged the above, its perfectly fine, just the yellow warning to the right.
