Comment #11 on issue 656 by tu...@tudorgirba.com: [Glamour] Finder doesn't copy browsers inside its panes http://code.google.com/p/moose-technology/issues/detail?id=656
The visualization was not useful to identify directly the cause, but it was useful to provide a hint: it showed that the same renderer object was being announced to render multiple Glamour objects (the red lines). That meant that the the announcements were not copied properly when we copied the Glamour objects.
