crash on deletion of selection that includes last measure of score

Windows 7, GIT commit: 3e51505

1) use Promenade, or any score
2) click empty spot in last measure to select it
3) hit Delete

Result: crash

Seems to happen for *any* selection that includes the entirety of the last measure of the score. Debugger shows selection().endSegment() is returning 0 in Score::cmdDeleteSelection().
