Clicking a rest and extending selection more than once does not update Inspector

Ubuntu 14.04, GIT commit: d75fb33

1) new 4/4 score or My First Score
2) open Inspector if not already open
3) enter a single quarter note onto beat 1, measure 1
4) exit note input mode
5) click half rest at end of first measure
6) Shift+Left twice to extend selection to first note

Result: Inspector still shows "Rest" as element type

7) check "Small" box in Inspector

Result: either the half rest or the half and quarter rest are affected (seems random). If I extend the selection further (eg, click a rest then Shift+Right a few times), I find at most one or two rests are affected by the Inspector.

It is only the Inspector that is affected, I think. The "V" shortcut and other commands that operate on range selections work just fine. Debugging shows that MuseScore::selectionChanged() is not beuing called after the first extension, and hence the Inspector never gets updated.
