Crash on landscape

I got this when moving to landscape:

```
*** Assertion failure in -[UIView layoutSublayersOfLayer:], /SourceCache/UIKit/UIKit-2935.138/UIView.m:8803
```

the only thing that I've found so far:
http://stackoverflow.com/questions/24273202/dynamically-sized-uitableview-in-uiscrollview-with-auto-layout

kinda brutal solution. I didn't go deeper yet.
