Too much recursion when pasting the name of a page in wiki explorer's input

Follow this steps to reproduce:

• go to Main.AllDocs page
• switch to tree view
• paste Blog.WebHome or Panels.WebHome in the input below the tree

The browser hangs. The page is not responding anymore. I have to close the tab. If I paste Main.WebHome everything is fine, so it seems the problem is related to those pages. Also, if I type Blog.WebHome in the input instead of pasting the page is selected fine. On FF3.5.7 with FB1.4.1 I don't get any JavaScript exception. On FF3.6 with FB1.5 I get a "too much recursion" exception in the SmartClient JavaScript code.
