"LayoutView#each_annotation_selected" doesn't work

[klayoutmatthias]

This is one effect:

> RBA::LayoutView::current.each_annotation_selected { |a| puts a.to_s }
std::bad_alloc in LayoutView::each_annotation_selected
  <main>:in `each_annotation_selected'
  <main>:in `<main>'

another effect was a wrong offset of the ruler.
