Adding parentheses to notes causes crash

Using a build from the latest SVN trunk (reports on Mac as revision 2613) I have tested the fixes put in to resolve the issues I reported about parentheses on notes.

I can say that parentheses work well now when added from the symbols menu (shortcut Z) but there is a bug.

1) Select a note.
2) Press Z to get symbol menu
3) Double click left parenthesis
4) Double click right parenthesis.
CRASH!

It doesn't matter whether you do left-right or right-left.

What is causing the crash is that when a parenthesis is added, the note become de-selected and the parenthesis remains selected. When you try to add the next parenthesis it presumably tries to add it to the first parenthesis. This in itself should not cause a crash.

I think the sequence of operations outlined should be the expected behaviour. I do not think the user should be expected to re-select the note between each parenthesis.

Otherwise, Werner's fix to my earlier report is great. I have tried the Small Chord and the parentheses track properly now. Excellent.
