Talk page bottom with same category shown three times
I've inserted a category in the talk header, in a thread summary and in a single message: it works (the single thread isn't summarized actually and it looks so, but this isn't a big issue), but the category is shown three times.
This bug would be really annoying in the case of subpaged threads (e.g. subpaged village pumps with a page for each day with multiple threads in it, where every day and every thread is categorized, as e.g. in it.wiki or it.news, and where we will hopefully have transcluded threads, see http://liquidthreads.labs.wikimedia.org/wiki/Thread:Feedback/No_way_to_multi-home_a_thread%3F#No_way_to_multi-home_a_thread.3F_855 ).
