Bug in default plugin "event-logger"? "oldvote=0" then "oldvote=1" - what is this?

Question

I see in my logs that the q_vote_up and in_q_vote_up event is registered twice (but only for me as admin!). Example here:

2012-10-28 16:25:31	95.90.218.244	1	echteinfachtv	595250729713884472	in_q_vote_up	postid=3902    vote=1    oldvote=1
2012-10-28 16:25:31	95.90.218.244	291	Klausii	595250729713884472	q_vote_up	postid=3902    vote=1    oldvote=1
2012-10-28 16:25:31	95.90.218.244	1	echteinfachtv	595250729713884472	in_q_vote_up	postid=3902    vote=1    oldvote=0
2012-10-28 16:25:31	95.90.218.244	291	Klausii	595250729713884472	q_vote_up	postid=3902    vote=1    oldvote=0

Is this a bug in event-logger or could it be that the user somehow triggered the event twice in the same second?

Thanks, Kai

 

PS: The only difference I can see is "oldvote=0" then "oldvote=1" - what is that?

Answer 1

From qa-history-layer.php:

if($params['oldvote'] == '1') // unvoting an upvote
