Same tag applied more than once on the same pic

Hi

Today it happened something strange to me.
I was tagging pictures, then going to preferences to activate the
write metadata flag. While clicking on "Edit" f-spot freezed. When it
came back I had one picture with the same tags applied three times!

sqlite> select * from photo_tags where photo_id = 23704 order by tag_id;
23704|1057
23704|1057
23704|1057
23704|1287
23704|1287
23704|1287

I'm sorry I don't have any idea on how to reproduce this! :(

ciao
