Comment 31 for bug 1662544

I'm sorry, Stanislav, but what is the difference between

```
for layout in sorted(l.lower() for l in layouts):
    if layout != "default":
        self.layouttreestore.append([layout])
```
and
```
for i, layout in enumerate(sorted(l.lower() for l in layouts)):
    if layout != "default":
        self.layouttreestore.append([layouts[i]])
```
?
