@gnu2 Actually an error during posting is not a very rare problem. Usually a Server smartly handles this, logically "merging" two same Notes from the same Actor...
@gnu2 This could happen, when during sending a Note successful response isn't received from a Server (e.g. due to network problem), when in fact the Note was saved by the Server.. Later #AndStatus receives that sent Note as an unrelated one. Hence two copies.
