Note input cursor "backs up" upon creation of tuplet

Ubuntu Studio 14.04, GIT commit: 2c43586

1) new score, 4/4
2) note input, "7 C" - enters a whole note, cursor moves to next measure (all fine so far)
3) 5 Ctrl+3

Result: triplet is created, but note input cursor moves back to previous measure

It' a visual thing only; note input is correct as far as I have seen. This "backing up" happens also for triplets not at the beginning of a measure, but it's easiest to see in this case. It doesn't happen in all cases, but for the cases where it does happen - like this one - it's completely reproducible.
