Code Issues

- prevented crash when removing two (or more) statuses that reblogged the same status.

Browse Source 
When more  than one statuses points  to the same reblogged  status and
more the one of the formers  is deleted the first deletion will remove
the reblogged  status as well  and the second  will try to  remove the
same (already removed from db) status. This makes the program crash.
