1. created a page in English
  2. clicked "Translations" to create a new node in Icelandic (for example)
  3. deleted the Icelandic node
  4. visited the English node, then switched into Icelandic
  5. got page not found ("Síða finnst ekki") at URL of no-longer-existing Icelandic translation. Also, when visiting the "Translations" tab, it shows an item for Icelandic but a blank title (that is, not "Not translated" but completely blank), and just a "select node" link, no "create translation" link.

I expected it to just switch the locale to Icelandic but remain at the English page. That is, I expected, when deleting the node, to have the relationship severed so that I could, if I wanted to, create another translation.
